Where do I start!!! you have been away too long!!

Last week she was being particulary on edge snapping at me and picking up on anything I said, so I asked her why is she still at home, why does she not leave if she is so unhappy and my being there is upsetting her, she told me because she had no where to go, and I don't understand how much I've hurt her.
I just acknowledged everything and said that she needs to sort out what she wants and get on with it and went to bed.

Since then she has been polite, maybe even talkative a little, she is very inquisitive about who is calling me and who is texting me, think she is a little paranoid?

Anyway we are still in seperate beds, we don't really share much conversation, but when we do its polite and without any anger, the kids are great, I'm spending loads of time with them, i'm running most nights, I feel good, I've lost a fair chunk of weight, people have commented on it a lot, I've not had a drink in a month, I'm still on the anti-depressants, I think they are really working I feel great in me, just wish I had a marriage!

My wife is constantly asking how I'm feeling and do I think the tablets are making a difference, not sure if this is just idol conversation or a genuine interest in me and the future, but at least at the moment my kids are still living with me.

I am confident that there is nobody else involved, she doesn't go anywhere really, but it could be an EA?

But I cannot control what she does, so for now do I continue as it is or do I push her for an answer to what she wants and what is she doing about moving out?, I don't want to push her out but how long do we continue like this? or is she just watching the changes in me, she keeps saying that I can't keep this up, well we will see about that because I feel better than I have in years, so is she just waiting and watching before she commits to anything, I know it takes time to heel, so i need to give her that time.

Any thoughts will be welcomed.
