I should be over it but I'm not ..

How do you get over a break up with someone you just had a baby with and you can't stop loving .. how do you get over someone that you cry about daily .. he feeds me false hope and I know it's all bull shit yet I still make my heart believe it . I told him I wanted to be a family he says " it's goin to happen just let it fall in place " that's bull shit ... its all bull shit because he doesn't even call me he comes by maybe once a week an see the baby then we may chill talk and laugh for that moment then poof it's over . He doesn't ask if we need anything he doesn't help me or even ask if I'm ok ... he don't care at all and I just want to be over it but I can't ... I believe God changes things but people have to want to change and I don't see him wanting it .
