Is this emotional cheating, not ok or am I completely in the wrong?
Boyfriend of 3 years, live together. He doesn't have many friends but has a few he chats to every now and again. Doesn't go out much with mates. He has a couple of friends that are women, I've always tried to be cool about this as they chat but probably meet once in a blue moon. 1 of them is a lesbisn so not worried there. 1 lives over in a different European country, we live in UK. Obviously they don't meet really, he flew out to meet up/weekend away when we first got together so over 2 years ago now. That was the last time he saw her. She is now coming over here. They've been messaging General chit chat since Xmas. Sending normal, how's your day? How's work messages. And then also photos if their days which I think is a bit much. He's agree to meet up with her when she comes over.
The issue I have is he hasn't told me he's messaging her. Never brings her up in conversation and when I ask if he's spoken to any friends recently says no. I have had to go through his phone to find these messages. Yes I know that is bad of me. These messages had been archived even though they were constantly chatting. He told her yesterday that he went to a specific place and she asked if he had gone on his own. He said "yeah, I'm sure you would have liked it.'
He went with me. He never mentions me in messages and it feels like he's hiding this from me. I don't know how to bring this up as I know it will be turned back on me going through his phone and he will say that he has done nothing wrong. Surely hiding them, not telling me and not mentioning me to her is wrong?
