Guys im lost can i get some help?

basically ive asked this so many times but dont get any responces. my girlfriend/ex is pregnant and the day we found out she said she didnt love me anymore and hasnt been happy in the relationship for a long time. (i know all about hormones and her being scared and stress levels and stuff) in the relationship we were both very happy till the end and she refused to talk to me and when i said "honey if theres something bothering you please let me know so i may do something about it" she would say nothings wrong....so that left me confused. im 20 shes 22, we both have no friends and have been each others best friend for 4 years. i used to get angry at her and shout because she would call me a prick for coming home from work and turning on the lights (because she was insecure about me seeing her without make up on) it was hard but like all relationships i realise it takes work from both parties. and now shes pregnant....says she just wants to be friends and that she cant love me again, and that she will be raising this child alone and she holds all the cards. im not allowed to see the child alone....yet she hates my side of the family...so i have no idea what to do there...she thinks shes strong and she is very stubborn and wont even listen to her mum. i love her more than anything on this damn planet and would do anything to get her back, but she says she just doesnt want me because i "treaded her bad" now...FYI i hate drugs, i do not drink booze, im not violent, im a law abiding citizen, i tried to do romantic things, i bought her gifts, i made sure she KNEW she was the apple of my eye and NO ONE on this planet could compare to her the ONLY thing i did in her eyes that "treaded her bad" was that she had to ask me to hoover....i want to do the right thing by standing by her and the child (because well, it then leaves the path open for us to maybe get back together, and i feel its morally correct, as the child didnt ask to be brought into this world) but i want full involvement with my kid...i dont want to say on the day its born "right i gotta go see ya" it would be too heart breaking.....WHAT DO I DO!!!! IM ALONE AND I LOVE HER AND SHE SEEMS TO JUST BE....CALLOUS!!!! :( HELP ME OH GOD PLEASE HELP!!!!! my email/msn addy is waddaydiddlydayday@hotmail.com...PLEASE HELP!!!
