I was feeling really low, I spent the day crying. My bf still went out drinking all night

I was supposed to go visit family but I was in too much of a state to go. And he saw me crying but still went out.

I was on the verge of suicidal, he didn't know that. He said he was going out for a few hours and he would bring me back food.

It been like 4 hours and he still didn't come home, I called him to see where he was, he said he was going to the shop to get me food and then he calls and tells me to just order myself food.

He comes home and is outside drinking, tells me he's coming but he doesn't. I called him so many times, he said was coking but he didn't come. They were making so much noise, so I called again so he would turn done the music.

It wasn't until I left and went to go sleep in the other room that he came back.

I was having a break down and he just left me. He said it was because he had a busy week at work and let off steam.

Am I wrong for being upset that he left me
