I'm sorry but red flags for sure 😔
I can see a lot of red flags....
You’re not crazy or paranoid. You’re responding to real things you’re seeing. I would raise it - you don’t have to mention cheating, just that you feel like he’s hiding something from you, which is a fact
Girl to girl either talk to him or go through his phone! I know it’s an unhealthy thing to do but if it’s going to reassure or affirm your suspicions then you need to do it for your own sanity. My ex was very secretive and had lots to hide, not saying yours will be the same, it may well be innocent but it was only by me secretly going through his phone that I found anything otherwise that man would still be lying to me to this day
What milly said !
Also the other day his phone was on the side and I genuinely thought it was mine and saw a notification from someone on the screen which I read and didn’t recognise the username (That wasn’t anything strange it was just one of his friends I didn’t recognise) but I was like “who the hell is that? Oh it’s your phone….who is that though? “ and he got really anxious about it. It drives me mad
