I think Lee brings up an excellent point... Your boyfriend might not be ready to trust, whether subconsciously or consciously. And I tend to agree with you that only time will tell. I think the fact that you were able to have a calm, rational conversation about feelings on both sides of the issue bodes well, but I do recognize your fear as being very just and understandable. I think it might be worthwhile to continue the discussion with him, bringing up the question, gently, if he is ready and wants to start trusting again. And I would maybe stress the point of giving him time to really think about the question before answering.

I think the other hard truth is that no relationship is free from hurting each other, especially unintentionally...
