What is his deal???

So my boyfriend and I have an open type relationship, close to cucking, however he will occasionally sex other girls. It mostly consists of my fucking guys.

He constantly begs me to do it but the last two times I was with this guy, and most recently he actually took my on a date, my very first one.

Now my boyfriend said “no limits”, he didn’t care what I did, so I took the shot, we fucked twice and saw the lion king. It was amazing. He even said “if at anytime you dump your boyfriend, call me”

Now he doesn’t know that, he knows that my mom knew about the “date”, and she doesn’t know about my bf, as he’s 25, I’m 20.

Fit some reason, he’s pissed at me, and even told me to just date him, and I’m trying to figure out what happened. He won’t tell me why and just avoid the subject now. The night and morning before/if he was a complete asshole to me, so I didn’t feel guilty at first, but he started accusing me of liking him more, wanting him, I’m like “I’ve known him a week!”

Idk what to do
