Heh.. interesting topic.. definitely has my wheels spinning!
Heres my situation.. I don't know.. maybe it'll help someone, and thats good enough for me.
My wife and I met right after my last relationship - we met at a party but we're set up through friends. Anyway, We have now been together for 3 years and married for 1 year. Definitely my longest relationship.
At the start of our relationship the sex was great. I don't know if it was as often as most couples, but it wasn't bad. Within a few months our sex life started to slowly fade into once or twice a month. Something she always complained about.
Throughout our relationship my wife and I cheated on each other at different points for one reason or another. I only did for the first couple months of our relationship, as it wasn't that serious to me at the time and I was attempting to play the typical guy role in this society. My wife has a couple of times over the years as well.
Anyway, I had to live separate from my wife for the last 11 months for my job. During this time (as I have recently come to find out) my wife has cheated on me with multiple people on multiple occasions. About 5 people all together.
She could have moved here to live with me a few months back, however didn't because we were doing a "trial separation," which she has been convinced would end in a divorce.
Anyway, with that said, now all at once she wants to move down here and be with me. And, until the last few months, I totally would have been alright with EXCEPT for now I have come to terms with my GID and in all honesty, don't feel that much attraction for her anymore. I love her as a person, but I just don't want to be with her if shes wanting me to be the male she knows.
It'll be interesting to see her reaction when she gets down here.
