Well I know where you are coming from empress. My marriage was stale, dh took me totally for granted, was a total boring tightwad, but other than that a decent chap and wonderful father. But I felt like nothing. He also had a very low sex drive IMO.
I tries allsorts to spice it up but nothing worked. Then i eventually developed a huge crush on a guy at work. Who I then found out had had a huge crush on me for years. Once I had kissed him I felt I had to tell my DH, who I felt I wanted to leave by then. He was totally stunned and devastated.
All I wanted to do was leave the marriage but I knew I had do do it right because of the kids. So I told him I wanted to have an affair and had met someone else. I organised for us to go toRelate for counselling, to help us through the split. Weeks and Weeks of it. Gradually despite my infatuation I decided staying with my husband was what I wanted. Not least because he changed, which he wouldn't have done without the counselling. I also realised that to put up with what I was doing he must really, really love me even though his actions for years said otherwise (though he did tell me, somewhat mechanically, every night)
It took weeks before he could even see that there had been a problem! Eventually he asked if my 'affair had been sexual - it hadn't at that point.
Eventually I decided if I didn't 'do it' I might always regret it....and be tempted again. So I did.
I do wish I hadn't done it, truly, and he doesn't know what happened, and he would leave me if he did. But I'm sure I would have always regretted it if I hadnt and maybe I woiuld have been tempted later. The guy left where we work and moved away, thank goodness. I feel sure I wouldnt do it again.
Our marriage is IOK now, great actually, and I feel like I had a lucky escape, because I would have left him and then regretted it.
So I would say get some counselling. Fast. Because evryone says if you have done it once it is easier to do it again. Moving won't solve anything because there will always be men around ready to have an affair. The only thing to do is to have counselling to sort your stale marriage out.
But it is so hormonal, that total chemical crush feeling is like steamroller.
