Is OTHER wrong in the post ? POST : So I'm a guy and she's at uni, I'm on my gap year. Recently she started seeing a guy and keeps making it painfully obvious that he's "the Irish version of me". I thought, great, that's fine none of my business and I'm glad she's moving on. We had a small on and off thing in school a few years back but still managed to stay friends after. 

Anyway, recently she keeps sending me Snapchats at ungodly hours of them both in bed clearly naked (under the covers) after what I'd assume was them having sex. The sends wierd messages with them like "this guy woke me up at 2am!" or just one word messages like "hi" or "happy". Mind you this is usually out of the blue and we haven't been talking for at least 6 or 7 hours or even a couple days. 

To me it seems like she's trying to purposefully show off that she's having sex with this guy, I don't really care I just think it's weird to send that sort of thing to anyone. So I confronted her, told her I don't like it and it makes me uncomfortable and now she's mad at me saying I should be a better friend. AITA?
