I'm feeling really shitty and hurt right now and still she hasn't spoken to me days after this happened. I am really not a confrontational person so I've just left her to it so far.
Basically - on a night out, I was chatting to her DP in a completely innocent manner, we were laughing/joking, we get on well and have met several times before. I actually lived with them briefly too. She has never had a problem with this or us getting on well before. But a friend of hers (who I don't know) pointed us talking out to her and said it looked inappropriate, it looked like flirting, my body language was 'flirtatious' allegedly. I don't think it was. I think it may be relevant that I don't often dress up but I had made an effort with my hair and make-up and was wearing a tight dress, I looked really nice - I guess when I normally spent time with them I'm in jeans/leggings, hair tied up, glasses on. This is the only thing I can think of why it suddenly looks inappropriate or is upsetting to her that I was speaking to her DP. Another of her friends earlier in the night had been giving me fairly filthy looks while her boyfriend spoke to me too. So I can only imagine they all thought badly of me. Which is upsetting in its own way but whatever.
Anyway friend went off on one at me, wtf do I think I'm doing, all this shit. I got pretty upset at the time and her friend ended up intervening, apologising and saying she'd clearly got the wrong end of the stick. We made up somewhat, but at the end of the night as we were leaving, I was saying something obviously innocuous to her DP and she appeared and said 'oh you'd rather be with her, whatever' and stormed off again. Obviously alcohol affected everyone and things were heated because of that, but still. So that's the last thing I heard from her.
I'm really hurt firstly that she'd speak to me like that, that she'd think I would ever do that, and that she hasn't apologised afterwards. I genuinely did not do anything wrong, yet I feel guilty like I should say something to her first. I don't know what to do, I really value her as a friend and she's been so good to me in the past, incredibly kind and generous so this is all fairly out of character (though she's not a person you want to get on the wrong side of). And we are supposed to be holidaying together in a few months. So I'm torn whether to text her. I haven't heard from her which I did expect to, but she's busy and might not even see this as a big deal. What to do? :(
