Is NOBODY wrong in the post ? POST : Disclaimer for all who don't want a boring story. I'm just here to hear some opinions on this. 
So basically my cousins and I are pretty good friends and I always kind of enjoyed their company but since they got girlfriends they basically keep them around 24/7. Yesterday we agreed last minute on meeting today, hang out and maybe grab some food. I should probably mention that the last times we tried to meet up never really worked out just because I always had other things going (Birthdays, school work and other kinds of shit). So I always worried that they already think that I 'm constantly flaking on them (I don't blame them. It really did seem like it.). But this time I decided to flake out for real just so I wouldn't have to be the fifth wheel. Now my mom is just blaming me and talking with other family members about how I flaked on my cousins( she doesn't know about their girlfriends). I know this isn't a big thing but I still feel guilty. I mean I could tell them about my feelings but I'm sure they wouldn't understand (they're younger and aren't really the best people to talk to when it comes to feelings) and that's the exact reason why I didn't tell them in the first place. 
Anyways, I'm sorry if my thoughts were all over the place but I hope some of you could give me some feedback whether I am the asshole in this situation or not.
