Not paying any attention to me

So my boyfriend, of many years, has been paying more attention to unobtainable girls online. He never compliments me anymore. I used to get messages all the time, like morning beautiful or you're gorgeous. But now its nothing. I put all my energy in to complimenting what I know he feels self conscious in. Like, I think you look really sexy in those jeans, your arms are so muscular and strong. But I never get anything.

I don't feel sexy anymore, and sometimes I might even go as far as I don't feel loved anymore. I've gone through his social media profile and seen all these girls he must adore and I'm not really any different to any of them. I literally do everything these girls do and its infuriating that he wants to spend his time with these girls that don't even respond to him when there is me.

I confronted him about it the other day and he just got angry, said it was banter. I ended up being the one apologising and then he ignored me for a full day.
