Yes, Demo - sadly enough, you being pregnant will drive a commitmentphobia man away even more.... for what is a child if it is not having to be committed.
But if you are pregnant just give it time and he will come around - he just needs his own space to deal with how he is feeling (fears and all) and then he can work it out on his own.... but it must be on his terms at the moment, not yours. OK?

AND - a THUMBS UP for you having the courage to go back to school.... you are AWESOME!!
