Are really just women you can't get over the fact that they were not perfect for someone. Stop using human beings to get to someone else, it's fucked up!! You had sex with them, you spread your legs, it's not the Childs fault you got pregnant by someone you didn't stay with. Heck it's probably not your fault either but why make the chilld suffer? I think if they want to be in the Childs life let them, unless its danger to the child. Even if it has been years after, atleast now they are ready. You dont want someone to be in and out, better that they stayed away and got their shit together. its not about you or how much he pisses you off, its about your baby!!!!!!!!!!!
