Okay so I don't even know why I am asking this question on here, I guess I am venting more so. But I have this friend let's call her Sarah. We used to work together and knew each other just as work buddies. The when she left the job, we started hanging out socially more happy hours, I would invite her out with my girls etc. Long story short, we all went out of town for a girls weekend and she did some stuff that weekend that was not cool. We were suppose to be roomates, and I decided not to etc. So our evolving friendship kind of took a step back and it became akward because we still have to work together from time to time. I tried reaching out to her a few times to hang, but she is always tied up with this new guy of hers. A couple weeks back ( as she was in the office) she brought up Memorial Day weekend. I mentioned I was going to a BBQ that this new guy I am dating is hosting. I never invited her. She was the one who said " ohh that sounds like fun" so two weeks have gone by of akwardness (on her part) and today she called me at work for some work related stuff and brought up the weekend. She said"so is the BBQ still one because Adam ( the guy she is semi dating) and I are counting on you for the plans. we were going to go out of town but i told him you had a bbq etc"... OKAY A) you are on my semi strange list and wouldn't want my new guy to meet you that way and b) it's not my BBQ or place to invite people and I am already bringing two of my close girlfriends. Just because I am nice, I told her I would run it by him and see what's up but that it's not my BBQ. So my concern is, how do I nicely put it to her that NO she is not invited! Without her never talking to me again... and making things so very akward in the work place. She is one of those people who is cool, but snaps easily or so I'm learning if things don't go the way they want. Not to mention she bough a pair of concert tickets and invited my friend and I to go with her, then 3 weeks later wrote us an email asking for the money for the tickets since the payment is due... you invited us! So she keeps doing these akward things that she clearly doesn't see the way I see.

Just say that it's a private BBQ with mostly family and your guy wants to keep it with just close people oh and also you could say, he was expecting a certain amount of people to come and bought food for only that amount. Or.. he doesn't have enough room at his place.. tell her your excuse, say sorry and change the subject and if she snaps I suggest that you walk away.. I wouldn't put up with that crap, she doesn't seem like she'd be a very good friend..
