I'm sure he is, although I do know of people who have stayed in those situations without the sexual relationship. I even know of older people who "stayed together for the kids" but did their own thang...but not with each other. But, I don't think he's being truthful nor do I believe that their relationship is completely over...and for that reason, I am done.
I can't explain it, but before talking to him yesterday I was so ANGRY and UPSET but I still thought it would be really hard to end things. But after talking to him yesterday, I was so much more calm and I realized that I could move on and get over this.
