I met this girl a few months ago and we have met up a few times since then, and it is really obvious she's into me. It was always super-awkward for me as I'm gay and not into her, but I didn't really want to hurt her feelings so didn't say anything, and when her friends asked me if I was gay back in March I stupidly said no (to avoid upsetting her).
We agreed to meet up yesterday, but I purposefully made sure that we brought some other friends along as well, so that it wasn't just us...Anyway, a few days before we met up she asked me if I was gay (after seeing my Snapchat story) and I told her that I was. She was then acting all apologetic, saying she was sorry for asking and that she hoped I wasn't upset etc etc. I replied by saying I didn't mind and that it was ok. Tbh I was quite relieved because I thought it meant she would get the message that I wasn't interested, but clearly not.
When we met up yesterday with her friends, she was being really clingy, kept saying 'I love you' (in a jokey way that you can tell is actually kind of serious) and kept hugging me and holding my hand (despite knowing I was gay). When she left us for a few minutes, one of her friends said to me 'so are you gay or bi?', and I said 'well I'm probably bi because I don't really think you can ever label yourself as 100% anything'. He must've told her this later on, as today I've been getting texts from her saying 'you're bi, omg, I'm confused' etc. It's really annoying because she's probably interpreted this as 'He might still be interested in me', despite the fact that I told her friend yesterday that I didn't like her in that way.
Seriously what should I do? This has been going on for months, and even though she only found out I was gay a few days ago she seems to have gotten worse...
TL;DR, I'm a gay guy being continuously hit on by a girl, despite her knowing that I'm gay, and I don't know how to deal with this.
