Wife wants marriage with OM, is there any hope?

[mindsin]

Update - 7/1/14

My wife are very amicable towards one each other now. We spend an hour or so every night talking about our feelings, laughing and joking. The other day, she revealed to me who her OM is. It's someone that I know (in her professional life), but I don't know him in person and I've never met him.

I've also told her at one point that perhaps I was never truly in love with her, only to recant that position a day later and reveal to her that I am still in love with her (probably a mistake). But still, I promised to be open and honest to her, and that was my honest feeling.

We've also stopped arguing about the situation.

There are some key things that she's told me in the last 48 hours or so that makes me have a little more hope that she will return to me.

1.) A couple of months ago, she told me of a new favorite song she has ("All of Me" - John Legend). She told me to listen to lyrics and commented on how beautiful they are. I am a piano player and singer. As soon as I knew she liked that song, I learned how to play and sing it. I remember performing it for her one night, and she did not have much of a reaction. Fast forward to now. She revealed to me that this song was introduced to her by the OM, and that it was "their song". She then tells me that she told the OM that I played and sang this song for her. She told me that he got very upset and said he hates that song now.

2.) She indicated to me that she's going to miss the great sex that we've had. Strangely enough, our sex life has vastly improved over the past year, to little effect apparently, since she went and had an affair anyways. Here's the kicker -- She told me that she told him that I am better in bed than him.

3.) Last night, she said that she feels safe with me.

4.) After telling her that I signed up to an online dating site and I've received quite a few "likes". She immediately asked me why I felt the need to do that. Why would she have a problem with that if she just wanted me to move on? This morning, she said that she thinks I should try it and go on a date. Was this a mistake? Should I go on the date? Is she testing me?
