So FI and I just received an invitation to his ex-girlfriend's wedding.
She was the last person he dated before me, and they were together for over 3 years. I kind of feel a little weird about going to her wedding, just because the relationship ended so badly. FI's parents also tried to get FI to go out with her again after he and I were dating, so it's extra awkward.
What would you do in this situation?
