<human>: So I'm turning 22 on October 25th, and was planning on making a double-birthday thing with my friend C. (C and I aren't very close, but E (boyfriend) is better friends with her so it seemed convenient, also her party lands directly on my birthday.) 

The party was going to be at a club, but because of my terrible luck and forgetfulness I lost my wallet about two weeks ago. I have been trying to get my ID back but am having trouble and it really doesn't look like it'll arrive in time.

So today E asks me if he can still go to the club even though I'm not going to be able to go. At first I was like "sure, I guess so" but then thought about it for a while and am not sure if this is okay with me. I don't want to forbid him from going to his friend's birthday, but I really don't feel like I matter in this sense, like he doesn't really care to spend this time with me. Maybe I'm just being over-sensitive, I don't know...

I suppose I should mention also that someone is going to be there, this girl L who has gotten in between us quite a few times and has basically been toxic to our relationship. After a year of me being upset of her antics and constantly explaining/re-explaining to E about how upset she makes me and how uncomfortable I feel that she is going to be around him. I guess this is also part of the problem, I feel as if I'm being kind of immature about the whole situation... Reddit pls respond I don't know what to think...
