I don't think it was because I became sick. I was probably because I left the place and came back when she messaged me. Also because I asked her a second time if we could talk and she didn't want to while some people heard our conversation. I was quite discrete otherwise and didn't make a mess conversation wise. Anyways I don't really care if I made a fool out of myself, since I got the answers I wanted.

I just didn't see any options. I thought about it afterwards, but couldn't see any way to stand up for myself without making the situation worse. I think the best option was to swallow my pride and leave.
I'm not trolling. Though the whole situation felt like a sick joke. The way all her friends eyeballed me while I was getting high and she was fucking in her bedroom might just be my paranoia though.
