you don't need him obviously he isn't any good for you and your unborn child.Anyone that can walk away from some one that is carrying their child,and doesn't offer to help in no way possible needs to be put away.I know that you might still have feelings for this guy,i mean you was in a relationship for 3 years.But think about yourself and your child,he doesn't love you enough to say baby im going be here for every step of the way.Instead he disappeared like a ghost.At this point you have to be strong for you and your child,stop worrying about someone that isn't worrying about you.You need to be focus on this baby of yours,even though he might not want it, Its still YOURS.You have to give this baby twice the love of 2 parents.I really hope he realize how dumb he's acting,and try to be a farther to this baby.But if not you still continue to take care your baby like you plan to.I hope you find a man that's good enough to love you and your baby.Stay strong.
