i (f22) have been with my boyfriend (m24) for a year and a half. i love him with all of my heart, he is my best friend and i truly want things to work out with him. our current fight is because he chose to go out to bars with friends from school the other day, including about 5 girls and some of his guy friends, and he stayed out with them until 2am. i told him this made me uncomfortable because he just recently made these female friends at school, i don’t know them, and personally i don’t think making new friends of the opposite sex in a relationship is necessarily appropriate and especially not going out to bars, drinking and staying out til 2am with them. we live 2 hours away from eachother and we usually only see eachother about every other weekend, so inviting me is not necessarily an option either. he also avoided telling me the names of people going because he knew i’d be uncomfortable with it, but he wanted to go anyways. he can’t understand why this upsets me so much and that if i trust him then this sort of thing shouldn’t bother me. now i am questioning if i am the problem for having a problem with this although i truly don’t think i am being irrational. genuinely i need to know if i am wrong in this situation, did i pick a fight for no reason? is this a valid boundary to have or am i being immature.
TL;DR! I need to know if I unnecessarily started a fight with my boyfriend and if I am being immature by being bothered by something he did.
