We have all known each other since high school. I am really bothered by this. Sure, my fiancé is closer to them than I am, but still... Friends or not friends, when you invite someone to a party, you should invite his/her fiancé too! I got mad and asked my fiancé not to go, since I thought it was rude not to invite me. But he went anyway, which just got me more upset. I don't know if I'm overreacting or what. But it made me feel like I don't really matter in our group of friends. :/
