Wife staying out all night
	
	
		First a little background... I have been married for 22 years. We have 3 beautiful girls. I have been "caught" watching or attempting to watch porn 5 separate times.  The last time she caught me was over a year ago.  Since then I have been sleeping on the couch in the family room.  She has said if it were not for the kids she would get a divorce.  She has also said that I need to "win" her back or pursue her.  I have tried to do things like leave little notes that I am thinking about her and those type of things but it does not matter.  Each time we have a discussion about this it all goes back to "I have not done anything" and what I did to her.  She has also said it is going to take a long time for her to work through the hurt.
Now she is going out with friends and staying out all night.  She has said they are just friends but I know the majority of them are guys.  If I say anything it all goes back to what I have done to her.  The girls know we(their mother and I) are working on some issues but it still hurts them to see it.
Last night she stayed out all night for the first time on a weekday.  She normally takes the girls to school at 8.  The girls called me at 7:50 asking where she was.  
I do still love her and want to fix this but I do not know what to do.  I am not the most romantic person in the world for sure.  Our 22nd anniversary was on the 5th of May and although I did get her a present she basically ignored it.  She has also stated our whole marriage has been bad.
What would you do in this situation?
