Going, I'm replying because my H did something similar to me a couple weeks ago. It was not a party full of women, it was just a party he goes to every year. A big bash. I tried to get myself invited but he would not even consider it. Bottom line, the only recourse I had was to live with it. He knew how I felt. I was hurt that he didn't want to be with me. I know I should not have pushed as much as I did to get myself invited. I was pursuing.
In the end, I did the only thing I could do ... had a party of my own. It wasn't anything big. My sisters, great food, good wine. We had fun. It was better than sitting at home alone wondering what the F he was doing (or if OW was there).
He asked a lot of questions about it when he got home. Saw the leftover food, etc. I acted as if and told him all about the good time we had.
My H can be very independent. There is nothing I can do about it when he makes his plans ... except act as if and GAL. But it's hard as h#ll! Inside it hurts like h#ll, too.
MAKE YOUR OWN PLANS! Don't sit home alone. In the end, I was in a much better place being with, and partying with, my sisters. Do something, keep yourself busy somehow.
