Can't stop thinkin about my ex hurts so bad

[Stuck in place]

So i have only dated 2 girls in my life im 21 and the first girl i dated i was with her for 3 years and after we broke up i didn't think id ever date again i am a very picky person when it comes to dating and when we broke up there was one girl that was there for me and i fell in love with her right away but because i was with my ex when she liked me she didn't wanna wait for me to break up with her so she got with this guy and its been 3 years she stopped talkin to me cuz he bf and iv always thought about her iv been single since my ex and she has a kid now he is almost 2 and her and her bf broke up a few months ago and we started talkin and right away we jus took off and we started datin only a few days after she broke up with him we got together finally and i knew right away it was goin to be a challenge bcuz there was a kid involved but i fell in love with her and her son she told me all the time that she wished her son was mine and she said she loved me but we dated for a little over a month and all of a sudden she wanted to give her ex another chance for the kid i know its the right thing kinda i mean she jus wasn't happy with her ex and they always fought and in my eyes two fighting parents around a child is worse then parents not together in my experience and she said she loved me but she just couldn't .. idk deep down i know she cares about me but i cant stop thinkin about her im in love with her she's everything i look for in a girl she amazing and i can't give up she's back with him doin good and its killing me its been more then a month and im still in pain iv tried talkin to other girls but when i do i compare them to her and its just not there everything reminds me of her i still got the stupid baby crib and toys for her son in my room every time i try to take them out i jus break down and cant do it im so in love with her iv never looked at a girl and felt that spark that i did with her she rarely talks to me anymore how can someone love you and say all the things they say to you and then just stop talkin to you... thats not love im so lost

One sided love. You loved her but she didn't feel the same. It's basically the overlying reason of why most, if not all, relationships come to a dreadful end. Don't try to contact her, Go No Contact and heal, And also improve yourself while on this rocky road.
