Is NOBODY wrong in the post ? POST : First off, using a throwaway for obvious reasons.


This is a bit of a rant, so prepare yourselves;


A few years ago, when I was a freshman in High School, I found out a girl I was friends with had a crush on me. I told her (in more words) that I wasn't ready for a relationship yet, and she seemed to understand. A little bit later, she dated someone else, but they broke up, and she kind of talked to me on and off after that, but I never really saw her. We'll call this girl "Girl A", for the story's sake. A year or two later, I met another girl, Girl B, and we also became friends, along with two other people in a kind of small "friend group". We grew as friends, but similar to Girl A, I never really hung out with her.


Fast forward to this year. I've never been to a school dance through all of middle or high school, and it's my last year of high school. I want to go to homecoming, but I want to have a date. I figure it wouldn't be a bad idea to ask Girl A to homecoming, since we're still on good terms, and I know she at least *used* to like me. I decide to talk to my closest friend who is a girl (not to be confused with a girlfriend) for advice, Girl B. Girl B talks to Girl A beforehand to find out for me if she'll say yes, and then helps me figure out how to ask Girl A to Hoco, which I do. She says yes. However, I want her to know it's as friends, so I make sure to mention that. Following Homecoming, Girl A is talking to me more and seeming to get closer to me, but I try to be clear we're just friends. All of the sudden and out of nowhere, a member of the friend group with Girl B in it reveals to me that Girl B was sad I didn't ask her to homecoming, because she has a massive crush on me. I'm flattered, but when I talk to Girl B about it, I give her a similar "I'm not sure how to feel about it" response.


Now comes the really complicated part.


I go through a pretty hard bought of depression, and Girl B is super nice and helpful, and comforts me throughout. I grow closer to her, and we become semi-official "boyfriend &amp; girlfriend". Of course, being the loser that I am, I tell people that I now have a girlfriend to feel better about myself (Girl B doesn't mind, she thinks it's cute). At the same time, I begin to realize Girl A still has a crush on me, and a dilemma strikes when they both ask me to hang out on the same day. Being the completely rational and intelligent person I am (sarcasm), rather than dealing with it, I decide to tell both I am busy, and go to park by myself instead. Obviously, I need to deal with this, but I don't, because I'm very shy and antisocial about it, and I don't know what to say. However, today, I mentioned to someone from my homecoming group that I had a girlfriend. From what I can tell, she went and told Girl A, who really likes me at this point, but I was stupid to let it go on like that, and now Girl A has left the long-lasting homecoming group chat saying she "doesn't belong there" and it was "a mistake to join". Obviously this is scary and freaks me out, since she's still my friend, but she's not responding to anyone, from texts or calls. 


I finally got over most of my depression and a ton of drama recently after most of my closest friends left me suddenly &amp; without warning for a different friend group entirely. Girl B helped me through that. Now, I'm worried about this. I really don't want to fall back into that rut, and I really, really hate drama like this, but I don't know what to do. I'm also especially worried about Girl A, because I'm afraid she might A. Hate me for this,  B. Do something bad to herself, or C. Create more drama around me in some way. But I don't know what to do, and I never see her, so I can't confront her about it. It's 11 pm and I'm kind of freaking out about it, I just wish High School would hurry up and end and I could leave all this drama and messiness behind, but it just seems to follow me wherever I go.


So the question is; am I the asshole for letting this go on? I know I should've said something, but is it my fault that this is happening?


Tl;dr: I took a girl who used to have a crush on me to homecoming, then found out a different girl liked me. I started going out with her, but the girl I took to homecoming didn't know, still likes me, and completely isolated herself when she found out today that I was dating someone.
