I went through something similar.  At the 3 month mark my ex told me he was dissatisfied with his life, and wasn’t sure he was really meant to be in a relationship.  He struggles with a plethora of issues, but one of them is his history of being hurt by women.  I was not as patient as you and pushed him to continue the relationship, and we did.

It was a disaster.  I wish so, so badly that I had had the foresight so say “I understand, I am disappointed but I wish you the best,” and let him go.  Instead we endured months of confusion and hurt and I regret it so much.

I advise you to let him go. If he decides he’s ready he will come back. I know it’s easy for me to say this but I have been in your shoes, and pushing him into something he has said he’s not ready for will hurt both of you in the end.
