my baby's father is in a relationship with another girl and now he's saying my baby might not be his when we both no he was the only person. even though she takes care of him n let him mess around on her and still takes him back i think thats what he don't want 2 leave is here taking care of him , cause he no im not gone take care of him. so he gone say ima wait and see till the baby gets here before i no what ima do. and i said what you mean and he said ima get a dna test and he dont want anything to do with me . he dont want me 2 have his number . and i was in the hospital friday and i got his number from his nephew since he wuhn give it to me and i told him i was in there and too come check on me he said no and how you got my number he wuhn worried about me sick he just wanted to no how i got his number. So now i feel alone cauz he wants to wait till our baby gets here and get it tested before he step in and help buy things .im so confused cauz i think he wants to stay with her cauz she buys him and i dont but if you have any advice for let me no what my next move should be.
