What do you think about me excluding my former best friend from my bachelorette party?
What happened?
We are no longer friends.
You should be allowed to invite anyone you want to your bachelorette party. You are not expected to invite people you are not friends with.
But I was invited to her bachelorette party. She also engaged in drunken sex after the party and didn't ask me to join in! She's so mean. Why would she do that?
You sound a little mixed up and twisted about your ex. I think you're right not to invite her and let go of the relationship. It's over; you need to move on.
