Well this may sound weird but I sent him an email.

I send him a lot of emails, it's easier for me. I'm totally wrapped around his finger and my new backbone turns to jello when he's around.

I made it short, sweet and to the point, totally polite and leaving the door open to work on the marriage. No more daily calls, confusing me with his relationship talk. And no more sex. I can not respect myself for having sex with him knowing he is not committed to me and is getting it elsewhere. If he never speaks to me again and that's all he was hanging on for, well at least my marriage ended with my self respect intact.
