Wtf idk I’m lost

So I’ve been dating my boyfriend over 2 years anyway, I found out only 2 nights ago he went down to a place with a few boys and shared a cabin with a 2 girls ( gurl that hates me in high school)

But he told me he was sleeping... I found out one year later. If he could hide this for so long what else would he be hiding

What would you do if he pretends to sleep but was sharing a cabin with a girl ???
