Howdy Amy,
Welcome to the Recovery and Discovery Affair Forum. I'm very sorry you had to find us however you've found a safe place along with alot of caring, sharing and wisdom from the folks here.
Hopefully the first thing this site provides new members is letting them (you) know you are not alone.
We all know how bad this hurts. First thing I had to acknowledge was this IS happening, I wasn't having a nightmare. It was real.
Next thing was to acknowledge my feelings. The more I tried to stuff them down the worse it got. Hopefully you have read enough here that you know everything you are feeling is common more times that not I believe.
You said<<<I don't talk to any of my friends on a regular basis anymore>>>. I'm a big believer in telling one close friend. You need that support Amy.
You said<<<I am somehow ashamed of this whole thing as if it is my fault.>>> This wasn't your fault. This was his choice. Don't forget that. Hopefully he hasn't made statements to that effect. "If you would have been a better wife, more sex"" blah blah blah. We call it blame-shifting. Don't buy into it.
You need to realize you have choices too Amy. You have the choice of deciding whether you want to reconcile and if so under what conditions reconcilation will happen. You are doing him the favor(for lack of a better word) by considering to give him a chance, not the other way around.
That being said you are so new to this. You do not have/need to be making any decisions on that now. Your job is to take care of yourself as best as you can.
What do you need from him that he isn't doing besides still contacting the OW? Why is he still in contact with her if he wants to save his marriage?
Here's a link to an article on emotional affairs. I hope it helps.
