I have a delima.. two guys.. one is a father to my daughter and another is a good guy who loves me & my girls.

here's the thing. i have 2 girl, 1 is 4 & that relationship didn't work out w/her dad cause as soon as i got pregnant he started to cheat on me. then when my daughter was 1 1/2 i met a guy from work & we started dating.he would constantly flirt w/girls & not tell his old gal friends that he was w/somone so he would get calls at all hours of the morning..he would cut me down & make me feel like i didn't deserve him, plus his family are from mexico so they tried everything in the book to try to make him break up w/me so they didn't have a white girl in the fam. well a year after dateing we decided to have a kid & then he started gettin ahold of his ex girlfriend behind my back & started puttin his hands on me, like pushing me down. i broke up with him and found another guy who treated me & my girls like queens but for some unknown reason i could not get over my youngest girls father. this other man still loves me but dont know how to move forward from the past. i cant help who i love
