Lonely and pregnant baby father not arund?

hi i am 4 months pregnant and my baby father does not talk to me at all. since i didnt have an abortion like he wanted he ignores all of my calls,doesnt call me back and doesnt speak to me wen he see's me in public. im trying my best not to get to worried during my pregnancy but i cant believe he is actin so heartless. he knows that this is his child but says he doesnt care and still doesnt want it. i just wish things werent this way
