Sooo I'm sure I'm just overthinking but want some opinions. My BF is 25 nearly 26, we don't live together right now but we are working on it. I still live at home about 1.5 hours away from him, we spend weekends together.
At work he has 4 friends, 3 are women, one guy, they go for drinks together on a Thursday after work. One of the women is new, she's an intern and only works there twice a week around uni, she's 18.
Last night I called him while he was out (urgent) I accidentally pressed FaceTime instead of normal but he answered anyway. Once I'd sorted what needed sorted I asked for a look around to see the pub and he said "say hi to ...." 18 year olds name. I asked where everyone else was and he said they'd already left.
They both live close to each other and he seems to be talking about her more then before. He's also a fair bit older especially in comparison to her being 18.
AIBU to feel a bit weird and uncomfortable about this? Why wouldn't they just leave when everyone else did?
