WAW is having affair, anyone with some advice?

[kenva]

I am 42 and she is 34. We have been married 9 years and dated 6 years. She sais she fell out of love with me.She is not physically attracted to me anymore, but she still loves me, like a brother.She would complain that I wasn't romantic enough the past few years. I now reailze I was depressed then. I was on medication, but now I have stopped them.I did neglect her.When she first brought up separating,7 months ago, I lost it. I got real emotional, now knowing I shouldn't have. I am more laid back now, not chasing her, but it is also killing me inside.i moved out for 3 months, to give her space, then moved back in, upstairs.Some days, she is hot and others cold to me. Getting real confused.
