I was DB'ing but just discovered an affair

[NTX_Dad]

After I posted my message above yesterday afternoon, she emailed me asking for help choosing her electric provider for her new apartment. LOL!

Last night she seemed angry about being caught and asked a lot of questions about how I found out. I didn't reveal much and we both went to bed frustrated.

This morning I got up at 5am and she was already up with folded laundry everywhere. I asked her what was going on and she said she had been up since 2am because she couldn't sleep. I asked why she couldn't sleep and she said her body is shutting down because of the guilt. I asked her what guilt and she replied "the guilt about what you found out". I just replied "oh" and went back upstairs.

She looked really bad... she looked very skinny, her face was sunken in and her eyes were very baggy. It's hard to not feel sorry for her. Something is very wrong with her. All of this behavior all summer is all over the board and she changes daily.

But the fact remains... she's really hurt me and I have to start detaching and protecting myself. It's very hard and goes against my nature, but I am not sure what to do.
