Me and my boyfriend have been together for just under 2 years. It’s our last year in high school and our proms are coming up, but as we go to different schools we cannot go together. I made it clear to him that it would upset me if he went with anyone. I’d get overly jealous like any girlfriend would. I told him I wouldn’t even think about going with anyone. But I found out recently that he’s going with a girl and he tried to keep it from me. I’ve had problems with him trying to keep things from me in the past, he’s also been dishonest and broke promises. I feel jealous that he’s going with someone and I’m going alone. Am I being selfish? Is it okay that he’s going with someone because it’s his prom and he should have fun? Am I right to be jealous?
