I'm wondering if I am justified in feeling let down by my friend attending OW's hen night? XH left me after almost 25 years for OW about 2 & 1/2 years ago. They're now getting married next month. When we split up , inevitably after so many years we had a number of joint friends and I have tried really hard to not mind that some of our friends have stayed in contact with him and therefore by default come into contact with 'her' too. I never wanted any of my friends to feel 'in the middle' between us and I made that clear in the beginning.
I'm not particularly bothered that they're getting married, as far as I'm concerned they're both cheats and deserve each other. I've tried not to mind that our grown up children are attending his wedding and indeed that my DD is being a bridesmaid or that some of our friends are going to the wedding, but I was floored this evening to hear from my daughter that one of my good friends is going to the OW's hen night! Her DH is one of my XH's closest friends so I'm not surprised he is going to his stag night but I am quite hurt that someone I consider to be 'my' friend is going to her hen night.
How would you feel about that? Am I being unreasonable?
Would you say something and risk losing her friendship? Or is the fact she's going to the hen night an indication of 'sidetaking' that you couldn't forgive?
