Me and partner have been going through a hard time for various reasons and recently, he's developed mentionitis about someone in work.
Started with constantly mentioning her, now it's a group chat with "taking the piss" which looks more like flirting.
He doesn't message me during the day or open messages but sends in the work chat during work and when I'm here (made sure I didn't see him sending anything).
Now it pushing for a night out with work and insisting I go (not sure why I'd want to go out with people I don't know when they'll sit and talk about people I don't know). Don't fancy going to watch him flirt with someone else.
Need some advice as I've felt like I need to let him go for a while but can't bring myself to do it :(
