okay so this is going to be long and probably very ventful for myself. if you get through all of this, i applaud you and if you can give me any advice, thank you so much in advance, really anything can help :)

okay so have a son, 3 months old, with a guy i dated a long time ago. we were friends first, dated for over a year, broke up but still hooked up. finally we were ending it and i find out he has a gf, two weeks later i find out im pregnant. he tells me he misses me first and then his fam finds out and he gets mad and wants nothing to do with me but everything with the baby. we meet up one day (i was at school so i came home every couple months during pregnancy) and we hook up and i find out he cheated. tell his gf cuz he wants and he blames me for the break up. well for the rest of the pregnancy he is distant, ignores me and he goes out smokes and drinks all the time with his friends. he tells me he was distant because of the fact that he didnt wanna stress me and argue cuz he knew we would if we did talk. well things are like that the whole time and we did try to work things out (talking wise) before i was due but it wasnt working so he wasnt there when the baby was born. i called him right after and he came right away and he was there. well, court papers are settled and he sees him twice a week at his house and he had to call my parents (because im living with them to tell him hes in it for our son) to come to my house. well its 3 months now, he finally just called my parents, he argues, hes late with child support, he ignores me time to time (esp. on the weekends) every time i go to his house everything is good, im usually doing my work or something and he tries to put his arm around me and kisses me. i dont do anything about it because i dont know how to bring it up that im not down for the hook up since im sure he is trying to date someone. regardless i dont wanna make it awkward you know? well, anyways today i go over and we joke like we used to as friends and then he tries to grope me. i tell him no and he still continues. it was annoying and i finally said, lets go home. so i come home and hours later he text me that hes sorry that he acted that way and that it wont happen again. and i asked him why he did it and why is he bringing it up, hours later he responds that its fun and stuff but its time for it to stop and it wont happen again. so again i asked him why he brought it up and if we could have a talk about it because theres all this unresolved stuff from the past year that he wont talk to me about. am i being over dramatic? asking too much? i just wish i knew why he acted like this, i mean to get some? to mess with me? he has feelings for me? i have no idea. i mean i dont get why hes what some would call "bipolar" with me. like hes nice sometimes and then he ignores and disrespects me the next. i dont know what to do....i mean honestly deep down inside i hope things work out so we both dont have to deal with the constant moving of our son from place to place for his sake, but it has to be that way so be it but all this extra stuff i dont get why its there and like i dont think he serious in his text cuz i mean he tells me he hates me one day and hours later he tells me that he is glad im with him at that moment....


any insight from anyone would be wonderful, again sorry for the rant.
