Ok so this is a bit of a long winded one but I’ll try to keep it as short as possible….
A guy got intouch with me a few weeks ago (we have a mutual friend) I was getting weird vibes but our friend said it’s just the language barrier.
Fast forward a bit and he’s trying to kiss me etc even though I have a boyfriend.
I eventually text him and told him I don’t think it’s a good idea that we hang out anymore…. I thought that was it.

I was on a night out and saw him, I thought I’d be polite and wave.
The next day he starts sending me messages telling me I’m fake and he hopes I get what I deserve.

It’s got under my skin as I have identity issues and it’s really making me wonder if I am fake…. I do change my personality a bit when I’m around certain people…. Has anyone had issues similar?
Am I just overthinking?
