Thanks everyone.
I know I'm more upset about not getting to see my friend than I should be, but it's hard not to. My friend didn't promise to meet me this time so I can't say that she broke a promise, but still... It's hard to understand why she seemed to want to meet me and then when it came down to it, she didn't unless the family member she was with had something to do with it.
I tried to talk to my mom about it and all she can say is stuff like "you don't know that she didn't want to meet up with you." or "you're judging her by what person A did." It's true that one of my former friends (also no on here) caused a lot of emotional damage due to the way she treated me. I've tried hard to get past a lot of that and not judge other's based on what she did, but sometimes it resurfaces at times like this. I also struggle with feeling excluded and left out, so knowing my friend was here and didn't seem to put forth any effort to let me know she was here so I could meet her and her family member somewhere is a blow.
My mom also said things like "maybe she sent you an email and you didn't get it." even though I told her my friend would have sent me a message that she'd know I would get quickly if she wanted to meet with me.
It would be nice if my friend sent me a message, explaining what happened and why she couldn't meet with me, but I doubt she'll ever tell me the reason.
