Is this the end of my marriage?

[P17]

As an update.

I heard tonight that the people in my W's work (she works in a supermarket) now all know about her affair and the new boyfriend. She has been out of the house just over a month. I have been yet again overanalysing this to death but am trying hard to just accept it for what it is rather than trying to read her mind.

However for me this kind of sounds the death bell for our marriage. Not sure if anybody has brought their marriage back from this sort of situation or this far gone?

What I want to try is to allow me to use the pain, hurt and upset I feel to let me detach from her completely and stop the fear of losing her so that I can focus on me and not on her. I just find this the single most difficult thing to do though. I have half detached contact wise, but I still do things to see what her reaction is.

She still occupies almost all of my waking moments. It has only been one month since she left the house. I do tell myself this is natural after only this short amount of time and trying not to give myself a hard time about it as I have good days and bad ones.
