Hopefully, counseling will help. It sounds like something from her past has come back to haunt her that she doesn't feel safe to confide in you yet. I know it is hard but be patient with her and hope counseling starts to help soon. Maybe couples counseling would be good too. You might ask if she is interested. I don't know that this would be a good time to try for a second child. I think I would hold off until you two are back on the same page. It would be a shame to be bring a baby into this kind of upseting enviornment. Good luck.
