Delurking Onit after following your threads with much admiration and empathy for virtually the whole time. The similarities in our situations are striking.
I had to post now based on your comments about new guy, it literally made me burst into tears (and I thought I was past that stage!) I am also involved with a new guy, completely unexpectedly, but can absolutely relate to the feeling like "me" that you describe. All I can say is the way that I'm approaching it is to enjoy every moment and try but fail miserably to not overthink things.
To have that escape and be made to feel desirable by someone that I like an awful lot is, I think, something to treasure and most certainly enjoy!
Yes, the crap that goes with the breakdown of my marriage, the pain of seeing my DC struggle, the incompetence of my own LCB in dealing with any form of emotion remains and is there every day. BUT my new guy makes those times we can spend together just so lovely that I'm going with it for now...it's what I need and it's doing me good.
Sorry for rambling. You are doing amazingly and will continue to, I'm sure. The dips are just part of the shite but will get less, I know it.
