So about 5 years ago one of my best friends slept with a guy a few times all very casual. Fast forward to now and I’ve started to talk to this guys brother - we seem to be getting on really well but one of my other friends think I should tell my friend incase she thinks it’s weird and makes her feel uncomfortable.
My friend has moved on etc and I’m confused as to whether I’ve crossed a line?
A lot of time has passed and nothing actually happened with the guy I’m talking to - just his brother.
what does everyone think?
