Husband’s ex

So my husband’s guy bffs are still really good friends with his ex. So at random parties, the ex is ALWAYS there. Every football draft, she’s there. Every Memorial Day party, she’s there. We’ve never spoken to each other so it’s super awkward. I try my hardest to get out of going to any party she’s at. I feel bad though bc my husband wants me to go and he goes to everything I ask him to go to.

The thing is, she’s friends with all the girls there and they don’t talk to me when she’s there. So it’s REALLY awkward and I have no one to chat with which makes me feel even more awkward and upset. What do I do??? 😢
