My friend is throwing a party and my fiance is going without me because I work that day. Its for my friends mom and I don't know how to feel other than sad that I can't go. I feel jealous. They can't reschedule I have asked nicely. Idk why my fiance has to go when it's not his mom.  And the worst part to me is that it's at a place I wished we could have gone to for his birthday.
