Well I am really not too sure what to say to you about this. I guess he may be giving you the cold shoulder in response to you giving HIM the cold shoulder. Did you explain to him about your feelings being hurt after he said that stuff about trapping him with the pregnancy? Or did you just say "F" you and go on? I guess it may be possible that his feelings are hurt now and is just reacting the same way you reacted to him. I am really not sure. Good luck.
