Boyfriend left me at restaurant

Our relationship has been in the rocks with arguments. Been together 3 years. Anyways, He drove us to dinner and at the restaurant he was drinking and had a few beers. (I was going to drive back). while we were there a table next to us this girl started becoming real friendly with us and she came and sat next to me and was asking how long we’ve been together etc. she was telling us how her husband is out of town for months at a time, etc. I didn’t see anything wrong with this. The waiter comes and my bf tells him, in Spanish, oh yeah I’m having a ‘trio’ tonight. basically meaning he’s having a threesome?? Mind you, I didn’t see the girl flirting but she was really friendly almost flirty maybe. I immediately got super angry with him but didn’t show it cause I didn’t want her to see. Her friends saw that I was a bit upset (not towards her but my bf) and called her back. I immediately start going off (quietly) to my bf and he says whatever I’m going to the bathroom. He never does! 25 mins later he texted me saying he left and to not bother him again. I pay the bill, go outside and immediately start crying. People who saw me outside were comforting me and offering me a ride home. My bf then pulls up and I get in the car and go to his house. He then screams at me to leave and go to my

House. I should’ve but I was a total wreck. Like eyes puffy and I didn’t want my family to see me like that and it was 12am. Also my boyfriend’s guy friend said he doesn’t see anything wrong with him leaving me there.

It’s now the next day… no apologies NOTHING.

His friend called me saying there was nothing wrong with him leaving me there as it was near by the house. (5 min drive, 10 min walk)

Would you break up with someone after doing this?
