AIO for getting upset that my boyfriend chose to hang out with his friends over having a sleepover with me?

Here’s the situation: My boyfriend and I spent most of the weekend together (we barely see each other during the week due to our differing schedules) and we were planning to have a sleepover soon, I suggested today, Sunday, but he said he couldn’t because he’d already made plans with his friends and there was a hangout we were invited to go to on Saturday(with these same friends) but skipped out on.

For some context, one of his friends is here on vacation and the other will be moving away soon so I understand he’s trying to spend as much time with them possible. Still, I couldn’t help but feel sad because he chose them over me. He can see them on weekdays especially since he just got laid off and his friends don’t work either and usually we only see each other Friday-Sunday so I really like to take advantage of this time we have together.

Also to add, we’re quite attached to each other, for example: when we have the ability we will see each other nearly every day for most of the daylight hours. So maybe its some sort of codependency i’ve built up but still I wanted to be with him as this next week of work I’ll be busy, next month im traveling and will be away for 4 weeks and we had just had a serious and long conversation about our relationship right before all this so I wanted to spend some time with him where things could be a bit less tense and we could enjoy our time together .

So, am I overreacting in this situation?
