That's cool. Sometimes we have to.
I've been lucky with not having any online relationships. She didn't like me being online, but my wife trusted me. The last time a lady wanted to get too close, I told thanked her but said I'd stick with the wife because the lady didn't deserve to have a guy that cheated on his wife. My sense of humor interests them, and, even when I'm rude, crude, and vulgar, they find it a turn on.
But, as this marriage winds down, I just move on. I try not to say anything bad about her, even to my kids and grandkids, but they know. They tell me!
