I exposed the affair last month. But it seems she may want to work on her marriage. I noticed the phone calls (from his phone log) had dropped off after the affair. But for the last week seems to have picked up again.

Do I still do Plan B in this case, or try to do a plan A and meet his emotional needs . He calls often and seems to want to stay on the phone and talk. Yesterday he came by to get something and practically begged me to go have a cup if coffee with him. I declined.

But now wonder if I should move in now and fill the void she is giving as it seem she is not calling him as much but he still calls her but not frequently.

He says he still loves me but I did not show my feelings and we fought too much.

Now if she is not talking to him much and I am trying to fill his emotional needs can it backfire as we always want what we cannot have and now he does not have her. What should I do?

I still vote for Plan FU. You aren't married and have no children. Don't sign up for more heartache. Get out now.

Plan FU sounds like a good plan. Wish I could do it but would like to see if we can have a shot.

I did deal with the relationship with a very cold heart. Abused as a child and didn't know how to let anyone in. He has mentioned I never let him in. I never showed my emotions or cried. I would tell him to leave when I was upset with him. I would walk away from a conversation when I heard something I did not like.

In other words I did all the love busters in the book. The OW is very calm. I spoke with her and hate to admit she has a way of talking I wish I could master. She met his emotional needs even though she is married. He has been begging me to talk less,listen more. Argue less in the past 8 years together. I am finally taking a step back and seeing what I contributed to the break-up.

You should be using this time to work on yourself. You don't want to do anything too quickly because you could just set yourself up for a false recovery and even more heartache.
Are you going to counseling?
