To expand on the title, my girlfriend regularly flirts heavily with other people. It makes me really uncomfortable but she says I just need to get used to it and that it doesn't mean anything.
Is everyone in a relationship like this? This is my first relationship (she's had a few before) and I don't know if I'm expecting too much. I wouldn't dream of flirting with anyone else, but she says the reason I'm so upset is because I'm just inexperienced and that I'm not used to being in a relationship.
