WOW!!! Major changes happening! Not sure what to make of it or what to do next!

Recap... On Friday, I started enforcing boundaries by canceling service to my W cell phone. On Saturday, I realized that my W used the home phone to call the OM, one call lasting only one minute. I previously told her that I would cancel the home phone if she used it to contact the OM.

I decided to wait a few days before taking action on the home phone. I wanted to see if she would try to call the OM again while I was at work. I checked the call log before I left work on Monday. No calls were made.

When I got home from work, I saw that my W seemed to be upset. She started following me around the house, saying very little, and looking like she was about to cry. Sure enough, she laid on the bed and stared crying. I asked her what was wrong. She told me that she was upset about everything that has happened. Then, she started apologizing over and over again. She told me that she never meant to hurt anyone. As she started to calm down, she told me that she got a new cell phone. I reminded her that even thought she had her own phone, she could not continue the A in our home.

She told me that wouldn't happen. She told me that she called the OM today and they decided they were going to stop talking to each other. She didn't go into detail and I didn't ask.

When she was upset, she seemed to regret what had happened. While consoling her, I told her that everyone makes mistakes. I also told her that no matter what happens between us, everything will be ok.

She did not bring up reconciliation. I did not bring it up either.

The rest of the evening we were friendly with each other. She has slept of the sofa the past few nights. Yesterday evening, after our talk, she started complaining about how uncomfortable the sofa was, as if she wanted me to invite her back to the bed. I stayed silent. She slept on the sofa again last night.

What do I do now???
