Hi there. I've been dealing with real life recently and I honestly ran out of ideas who to ask so I'm just going to throw it in here. Also going to start quite unoriginal.
There is this girl. We have been talking for long damn time, understood each other pretty well (or so I thought - I'll explain later on), doing stuff and whatnot. I've figured out that I'm in love with her and things started to move on a bit, at least that's what I thought (again, later). I was actually ready to finally tell her that we might want to hang out more and whatnot. I even planned to go out with her next weekend, but... well, it didin't work out for reasons provided beneath*. To describe her in short - responsible, school president, always busy but she also liked to have fun from time to time and whatnot. Also, quite above-average looks, but that's not exactly relevant. She had a phase few years before when she got drunk (to the point of vomiting and making not-exactly-ambiguous propositons) a lot and stuff, but came out from it... at least that's what I thought (yeah, again).
Then she went to one of her friends birthday party and that is where the hell broke loose. At the time I was somewhere else but we were writing to each other the whole party until the end and she was supposed to text when she gets at home. It took her longer than expected because she meet a guy, the said friends brother and they spent some time together and then he drove her home. Enough to say, I was kinda baffled when she said it to me (at 2AM, eh) but didin't want to jump into conclusions. But apparently, the worst expectations came true - they both literally jumped on each other. They instantly started to spend whole days together (by whole days I mean literally, the only time she isin't with him it's at school (yeah, we're still there and you may consider it some retarded kids problem but, well), and even then she sits on the phone all the time, something that unbeliveable before). I was really confused on what to feel, at first I thought it might have been "humanitarian rejection" since she didin't have any feelings for me and I was supposed to be friendzoned, but the more the time progressed the more complicated the whole stuff got. She broke contact with most of her friends, and some of them are irritated with it, since she has "changed" The worst case is proably the sister (the one who held the birthday party) of her new boyfriend - she is actually horrendously angry at the whole situation. She also ceased to talk to me, not in the offended way (at least at first) but she just stopped caring if I didin't spoke first. In the time period of a mere month, progressed from nearly complete strangers to the point she spends night at his home when there's nobody else around which is quite often. She also apparently started drinking a lot again, hanging out with people who aren't exactly concerned about much except another party, drugs and changing their boy/girlfriends each week.
I tried to talk with her and I did, three times. She doesn't know what's the whole fuss about and is angry that people even dare to say that it went too fast and that they're happy together and have some quite serious plans (FUCKING MONTH). I finally told her that I also have feelings to her and I'm... a bit concerned and well, I learned that she didin't even liked me, she talked to me out of simple politeness and I was honestly quite annoying. Also, for some goddamn reason she told me that they didin't only "progressed" in the emotional sense - but also physical one, if you get what I mean (EDIT: She was also apparently drunk at the time, which may explain the "confession"). I also tried to talk with her best friend but she also told her that it's not exactly normal but she also lost hold of her. Of course people also noticed what is going on (no damn suprise, we were close...ish before and then it was easy to connect the fact I'm not exactly happy and that she got a boyfriend) and told me that they don't exactly understand what happened because she apparently was saying she likes me, maybe even more than simple friend, but in the end they don't want to interfere. I know that I'm not exactly without fault in this thing, because well, she got into a relationship and I told her what I feel and generally speaking, I'm meddling with her life but...
You can imagine I'm not only fucking enraged (I had to get stitches on my hand after I saw them together since apparently the lamp post was responsible for all this), confused, humiliated, sad and hurt... but foremost I'm scared. I'm scared about what is going on with her. Her grades dropped, she stopped really caring about anything except him, not to mention that at the best time of all, her family is going through... tough times. I have literally no idea what to do - she doesn't want to speak with me, but I can see something wrong is going on. I'm don't even have delusions that we might get back together, but... well, holy shit.
TL;DR
It's complicated.
* Later on I learned she went to the same place I wanted to go with her with him. Fucking A.
