Am I being unreasonable?

Hi so my girlfriend is in Ireland and this morning I woke up to her sending me videos of her walking back from the club last night and then one of some random guy asleep next to her on the other sofa who at first she told me was gay then when I was awake she said he wasn’t. It was only then two in the room and 100% I don’t think my gf did anything or had any intentions of doing anything but it’s still just really upset me at the fact she hasn’t thought how it could make me feel seeing that? Am I being over reactive here ?
