hello so lost just need someone to listen

Idk if iam in the right place or but I have been having issues with my girlfriend well now my ex as of a few hours ago she has broken up with me she said she doesnt love me anymore and that she loves me still but that there's nothing there anymore . For a better understanding iam going to tell you how we starred as the perfect couple to nothing but hate.

We first met when i was fourteen she was goin ut with one of my good friends then they broke and we started talking it.was great everything was going good we fell in love
Lot of hard times but we always did it together then at 21 we had a bby life was beautiful it was perfect but then something came over me I felt Like I had to go out and not be tied down well that's when I started cheating and thinking that I didn't need her anymore I left with some other girl for three monthes then I start missing my family and want her back I dump the girl I was with to go back with my bby mamma well for a few monthes things are going good then I get into this deep deppression about what she did while we weren't together she had sex with a few guys and it drove me nuts but she stood by me even when I talk foul to her and called her all these names. But now it seem like the tables have turned but I was getting very addicted to weed it was consuming me I told her that I needed it for my deppression I told her that I would quit but I never did....

I no this probably doesnt make any sense iam just so hurt we stay with her parents iam in her little brothers while she is sleep with our daughter I just need some one to listen and talk with me please help
