My GOD, this is like reading my own situation. As far as possessions, I said the hell with it, the are just objects.
When you first move in with someone they have crap from previous relationships. The important part is that she is home.

The contact with the POS sucks, I am dealing with the same thing.

I view the affair as now part of our lives, we can't deny that it ever happened, but, we aren't going to drag it up every day and rehash it out. I hope that the saying "this to shall pass" rings true.
