Being treated like a step child

I feel like im a step child to my own father. He treats me like im not alive he only comes to me when he has problems with his gf. He treats her kids better then he can with me and my sister we feel like we are out in the cold. I feel as if im not good enough to be apart of his life it makes me cry when they have family dinners and i dont go they go on trips and im left in my apartment alone they try to be nice only for one reason. My dad pays for everything i dont think he should marry her its a bad idea and i told him this not only as his son but as his best friend but he wont listen to me. Maybe because im right She has done things to him and he still goes back to her hes a fool and i dont know why he would put her before me. I think its so stupied to put your real family before someone you met 6 years ago. I was the only one now. Im not he treats her 6 year old kid better then me. Thats why i feel like a step child. My birthday is coming up and all i really want is a Macbook Pro 13 inch laptop and he told me he dont know what hes getting me. Well if his gf wanted one he be like ok baby i will get you one because i love you. Save it i think its bullshit just because she shows her tits does not mean you deserve it. He got her all this work done on her body. Then used it to see other guys its a complete mess. He does all the things she needs done he cleans cooks i think the reason she keeps him around is because hes her butler and nanny all in one. It makes me mad she puts on a smile and thinks everythings alright. She has it all twisted then because i will not let them get married its wrong i belive she need to get her head on straight then they should think about it. I feel like im the adult here in the house. He does everything she can think of. On top of it she tells him if he losses 20 pounds she will marry him i think thats fucked up if so shes a cold hearted bitch. he needs someone to take care of him too like my mother she may get on my bad side but i love her and he had to fuck around on her it breaks my heart. He buys her everything she wants cars houses shes spoiled and it really puts a hold on alot of thing i enjoy when he tells me we will hang out but then when it comes time he either does not show or comes with the 6 year old it really messed up how we were. I feel as if they wernt around he take better care of himself he has to put his heath on the back burner to be her nurse and that makes me mad because he has kidnee stones and he ends up in a bed somewhere i will kill her he need to stop spending money on her a relize if he does not pay any mind to me or my sister we will be gone for good because he may be are father but still he is Neglecting us i think its time he puts them on the back burner. I think its wrong that he has to go to back to school night for a 6 year old that is not his and on top of that its my birthday so im out in the cold like wtf is he thinking. I wanted to go to canada but he had problems going even if we went i didnt want his gf going but he would have had to bring her anyways because hes like whipped and i think she holds his balls in a glass case thats just my view on that subject. I know i am his son and all that good shit but he has to think about the real kids he has he needs to stop being so up tight and do what he wants. She telling what to do he buys her what she wants its bullshit if she really loves him she would not do the things she did i know we all make mistakes but come on really the guys down and out and she cheats on him with another guy in there bed if you ask me thats fucked up. Then theres her older kid shes a super cunt to the extreme she thinks she better then everyone because shes a cheerleader so what she should take her pom pom and stick them up her ass. Her mom thinks shes a good girl i think they are to blind. She throws partys when there away she smokes drinks and does pot is that a good girl i dont think so. I know im not perfect but if she relize that ppl are to nice for her shes spoiled to. When im over his house it feels weird to me like i have no part in their life togther i have trust problems and what has happen in his like with her i dont wanna end up like that. I try to get on my feet but then she gets in the way of plans we have. I just feel that if he had time to spend with me we are not as close as we were i use to be his buddy now he has a 6 year old take my place i feel that if he get his head out his ass he relize thatme and my sister are the best things that could happen to him but he is to far up her ass to relize that. I try studing for my drivers test and he tells me were going in a week and then something comes up you should not keep a promise that you cant keep he makes many of those. I think its pretty sad that he cant see that im reaching out for him and he looks the other way like nothing happened. i love him to death but there comes a point in a mans life were he needs to relize that its time to have time for yourself. he never has time to his self because hes food shopping for her house he stocked up her house well i get 20 dollars some days to eat how about a home cooked meal. i have only had dinner there a few times not alot there do everything togther i feel since i have moved by him that im to much to handle or maybe he likes being with her more then me. I have a problem with the house in flordia its amazing but i didnt want the small room her oldest got the biggest room besides the master i told him how i feel he stop me to suck it up i got blmed for everything i would rather live with my friends then that evil little cunt who gets her way she thinks shes hot shit i wanna punch her in the fucking face. Then there was a time i had a house fire he could not come because he was sleeping at 2 a.m in the morning were your fucking kids you should have got in the car and came to help you were worthless then you didnt do shit i was homeless with my mother and sister and her father my grandfather had to come and put us in a hotel for awhile it still bothers me that it happen and he was no where to be found to come see us i lost sleep and i had no clothes nothing. I was freezing it was winter when it happen had to spend the night in the police station so i was warm. I feel is if he was gone we be happy i know its selfish but he dont need her shes a smut in all defences idc i really dont give two shits what they have to say i think its so stupied that she does thos things to him i understand he loves her but shes not worth it he snuck around his bad and when he trys to do something to find out she flips is it the reason your a dumb brunnette and your hairs not real, your boobs,your ass .your face if your going for the barbie look its not working for you sweetie thats my take on it.
