New to this and hating it.

[Jannie]

I found out the friend is actually only 21 instead of 23. Wow. She was born the same year we were married. Anyway...he showed up on Tuesday (unannounced and uninvited) to return the Six Flags passes. The kids and I were on our way out so he was here about 15 minutes. I was very cordial. We have texted twice since then. Once about the kids and another about D's truck. I find it easier to not have contact at this time and to keep it cordial when we do. I am kind of numb about the whole situation at the moment. I stay busy with my kids and friends so I don't miss him. I don't know if I have detached or am simply coping. Seeing and talking to him usually causes arguments which are better off avoided. His behavior and actions continue to embarrass me but friends tell me it's on him, not me. People also tell me it's obvious he is in a mid life crisis and acting foolish. He does not believe this of himself. Any advice on what to do in the next few weeks?
