he doesn't want his baby now ..

its been 18 year & 6 months since my last pregnancy..he didn't have any kids, i thought he would have been happy but instead he lost all contact with me & says he's not ready..I'm so hurt & pissed i would like him dead..right now this some childish Unforgivable act he's doing. what should i do now just let him go and adopt my child out.to a family that cares& will have love..I'm so lost right now!!
