I (19F) and my boyfriend (22M) are currently doing long distance. I have a Halloween party I wanted to attend next week with my friend, her cousins, and her boyfriend (all of whom I haven’t seen in a while.) This year is my boyfriend and I’s first year together, and I don’t know how he is with the whole “significant other going to a Halloween party without me” situation. I asked him today if he was going out with his little sister to take her trick-or-treating and he said no, he was gonna stay home and not dress up either. Now, I feel like I’m obligated to do the same. We’ve both been cheated on in past relationships, and I don’t want to do anything he wouldn’t like. I haven’t asked him about it yet, nor do I know how to approach him. He’s only said not to wear anything sexy (which I respect ofc. I’d be the same with him.) How do I make sure he feels secure while I still get to enjoy the party and see my friends?
