I (M18) have been friends with there two guys (M19) since middle school, but it seems like they don’t want to hang out with me anymore, what should I do?

I (M18) have never really had many friends, and I’ve never been very outgoing. There’s two guys (M19) that I’ve been friends with since middle school. They were two of my closest friends, and they’ve been the only ones I’ve talked to/ hung out with recently. A couple weeks ago was my spring break, and I tried to make plans with them for weeks prior to break. They said they’d be able to. On the day we were supposed to hang out, neither of them answered any of my texts, but then texted me late at night, when they were both already hanging out, if I wanted to do something. I didn’t even answer, then one of them texted me the next day asking to do something and I didn’t answer. It’s been about two weeks since then. I’m wondering if I’d be in the wrong if I just stopped talking to them. They’re my closest friends, but this made it seem like they really don’t even wanna be around me.

Tl;dr: I (M18) have been friends with these two guys (F19). I tried to make plans with them, and they said yes, but then kept ignoring my texts and answered each other and hung out.
