You know, I was once in this same situation. Well, I wasn't married but I had been cheated on by several women. Apparently when I was younger I was very cheat-onable. I was a very patient, understanding kind of guy. Quick to accommodate. Eager to make things work.

I once had a girlfriend, after that fact, who had a similar friend. He knew her longer than I did. He was always interested in her but she turned him down. I told her that I wasn't comfortable with the fact that he would always try to seduce her and she agreed that she would not hang out one-on-one with him.

Of course, one day she tells me that she's meeting up with him to hang out. Make a pizza. Watch a movie. Normal things.

Me, being the infinite respector of women that I am, told her that it was fine. How could I not? I'm not some controlling kind of asshole who would tell her who she could and could not be around. Did I like it? No. But it's 2019 and she is free to go where she pleases and associate with whomever she wants. I had to accept that.

When it turned out that she did have sex with him that day, I broke up with her on the spot and told her to never talk to me again.

You don't move past these lessons. You don't cope. I made that mistake and I let a woman make a fool of me three times. It's not going to happen again.

Now, ask yourself if you're going to be a cunt like me and allow it to happen to you over and over and over before you finally learn to stand up for yourself?
