I have a horrible pit in my stomach.

Boyfriend has a friend who recently reconnected with and they’ve been talking non stop for 3 weeks.. I’ve brought up and fought with him last week saying that they’re interaction has made me a bit uncomfortable that he could keep her as a friend but to be more transparent and include me...

Well today I thought he was being shady with his phone and the moment I got up he opened up his message from her and I came back, peaked at his phone because he was turned away from me and they were talking about fishnet/ underware.

I’m pissed. Do I have the right to be angry?
