I can't imagine a shock like that. I am glad he finally told you.

In addition to any couples counseling you do, I would suggest finding a counselor who does not know the two of you at all to provide counseling services to you alone. I worry that couples counseling services provided by a church where people know you two as a couple and have an expectation that you will marry will pressure you into committing when you might be better off going your separate ways. I don't think I am phrasing that exactly the way I mean it.

Like the poster above suggested, I think time is going to be a big part of this. That is a big betrayal.
