Upset and confused! How would you react?? Long read

Ladies, I'm on an emotional roller-coaster right now!

What would you do if you were in my shoes?

My guy is a truck driver, he works 12-18hr days. He called me to see if I would drive him home (we live together), because he had already fallen asleep driving twice today.

So of course I say yes, and have my sister drive me up to him.

We get into town and he wants dinner, we stop in at one of his favorite spots and by the time I have my food, they tell him they're not serving a menu tonight.

He gets pissy and LEAVES ME THERE! He got pissed off, stormed out and drove off.

As he was leaving he said "text me when you leave so I can get my girlfriend out of the house by the time you get home".... WTF?!

I don't know if he was joking or not, or if that could even mean anything else.

So I had to pay the bill and go. It's raining and cold out, no vehicle, so I just started walking.

Walked for about a half hour before I got picked up and they took me to my sisters house.

I don't want to go home and see him, I'm pissed, but its MY HOUSE!

I don't know how to feel, he's NEVER done anything like this, I also don't know what to think about the "girlfriend" thing... we've been together for 5yrs.

Should I just go home? I have sooo many mixed emotions right now!
