Last night my bf and a bunch of our friends were out at a club in Minneapolis. Anyhow it was hot as hell so we decided to go upstairs and stand by the entry way for a smidge to cool down. Then I noticed that about 5 feet away from me was a guy I used to date. He was trying to get me to go over and hug him etc and I pretty much blatently blew him off. I felt like a bitch and when he saw me a couple of other times that night he gave me really nasty looks, but I didn't feel like that was respectful to my bf or something I was comfy with. I know that if one of my bf's ex's was wanting to hug him and catch up I'd not be the happiest girl in the land. Should I have handled it differently or was it okay to be fairly impolite to avoid a less than comfy situation for my significant other?
