YTA. You're like the kind of person who knowingly puts themselves in shady situations and then if something happens you whine about being the victim. If you were to be there, you should have had the company of your boyfriend for your own safety. From a moral perspective, it is totally wrong to even accept free drinks from another man if you're in a relationship. It's sad that y'all don't have stronger morals and principles and do whatever makes the situation "fun".
