Is OTHER wrong in the post ? POST : AITA for being mad at my friend? 

So last night was my birthday and me and some friends got together to celebrate, we met at friend 2's place to pre-game a little. One of my friends (friend 1) was from out of town, who I hadn't seen in while and while we were walking up to the bar I offered to get everyone's tab. I'm pretty well off and just wanted to thank them for celebrating, they had offered to get me a drink before hand but I planned on drinking a lot too.

Friend 1 asked me why I'd do that and all I said was that they are my friends and I can pay for it and that was that. So when I went to the bar and said I'd cover it, Friend 1 said no and said he and my friend 2 we're covering. Now after that I was decently drunk, it was my birthday so you know, but I heard friend 1 saying to friend 2 I was being really passive aggressive about the tab, like it bothered him. He was right next to me and I could clearly hear him but he wasn't talking to me, still I asked him about it and he told me to forget it? Later after that he was actively ignoring me the whole night and excluding me from all conversations, specifically calling over friend 2 and 3 to look at something on his phone or to talk to just them and didn't say to me a word all night.

Later on drinking as much as I did I threw up on the walk back to friend 2's place, I was throwing up but I wasn't blackout, I could walk and stand nobody was holding my hair back per say. friend 1 started bad mouthing "seriously are you doing this right now?" "whats your problem lebowskiman85" I stopped to throw up for 30 seconds and then we continued to walk back, I didn't say a word and just went to sleep.

I know I was drunk but I cant help to think friend 1 was being a passive aggressive asshole or AITA? I'm really confused on it honestly.
