You know what, you made mistakes in the past and owned up to it. You admitted it to him. Now he seems to be holding everyone of your past transgressions against you.

My opinion:
1. IF he wants to stay in this relationship, he really ought to turn the page and let the past go. Bottom line: you did *not* cheat on him. The past is dead and buried.

2. Also, IF he keeps harping on about it you need to think whether you want to put up with his accusations and/or recriminations. Again, you did *not* cheat on him. So, in this sense, you have nothing to blame yourself for.

We all have a past. If a partner holds our past against us, again and again, I would not want to stay in such a relationship. HE also has a past and I would find it hard to believe that he was a saint in any and all of his relationships.
