I believe anxiety/fear will make you act like a totally different person. He may well know, and feel one way..but the fear and anxiety of what is coming may take over. He is a young father to be. Probably not wanting his child to be without him, as he was without his father. Must be very scared. Does he talk with you? Can girlfriend get through to him? maybe he doesn't want you to pay for counseling. Does girlfriend have any suggestions or know who he might open up to?
You are mom. I was told (re: easy child) there are just certain things HE will not share with mom. Many feelings. easy child's father also was absent from his life. Found out he did talk about that with others, never me...didn't want to hurt me. So it did weigh on his mind. told best friend that there is a man out there, a father, who doesn't want him.
I agree with ant's mom. File welfare. There is a lot of help available. Use it when you need it.
