my daughters father

I'm so hurt been crying every night before bed I can't eat I can't sleep. my daughters father had gotten into drugs started shooting up we aren't together he started to hit me then it turned into us fighting. it hurts so much when all I wanted was a family. then he tells me he doesn't love our daughter anymore. it kills he picked a needle over us he picked drugs over his daughter. I'm so emotional destroyed. I'm doing everything by myself but in the mean time I'm getting told he's telling ppl he's gonna take the baby when she's at the babysitters. I'm being told how he cries about his daughter but I won't let him see her. I'm so sick and tired of being strong and I hurt so much for myself but more for my daughter. she also has liver cancer . I can't seem to understand why or how he can do this to us. its messing me up so much. I work ten hour days I never see my daughter and am trying to get a second job just to do it all. Im just so broken.
