My 29 year old wife going through MLC, this sucks

[BSC]

Thank you SirPrizeMe.

Things stayed okay last night and this morning. When I got home from work she left to go workout and I played with the kids. Then we put the kids to bed together again and that was very nice, we even touched some more again. She is still being friendly. Then I went to a neighbors house to watch some of the hockey game.

When I got home she was still awake and we sat on the couch together and talked a bit(don't worry, not about R) and watched TV. She leaned on me while we sat side by side and I rubbed her neck, shoulders, and back for her. Ever since this started so many months ago she gets stress neck pain and headaches. She even put her head on my lap and we hugged. Then we said good night and she went off the the guest room and I went to our room. To clarify the guest room is over an addition that is not connected to the other part of the house. So when she goes over there it is like a hotel room and we cannot hear each other. She made a comment again about how uncomfortable the bed is and it really took her time going over there.

Then this morning, I woke her up when I left for the gym and she was still friendly and nice.

So today I feel good but anxious because she will probably go out tonight with her new friends I don't know and that always makes me sad. She has gone out more in the last two months than our entire realtionship. I am thankful that she has never drank alcohol and never will at least. But the reality is that things are looking better today than two days ago and I will keep up the PMA and try not to get caught up in her swings.

Now I have two questions and I know I am getting ahead of myself, but I know what to do when things are bad, but how do I handle when things are getting better. Specifically,

1. What do I do if she wants to come back to our room?

I told myself when this started that I wouldn't let her back unless she could tell me at the very least that she was willing to try to work on us. No guarantees but at least try. But, this was before I really thought it was a MLC.

2. What do I do if she wants to have sex?

My first instinct was to have at it(guy talking). But part of me also thinks it could confuse things. She often would use sex during any arguments to gauge where I was and control the situation. She knew if I turned her down she wasn't winning so to speak. But I am worried that if she reaches out in that way, turning her down could be a set back.

Again, I know I may be getting ahead of myself but I want to be mentally prepared over the weekend for these possibilities.

Thanks for the advice everyone.
