AITAH Because I Ended a Friendship/Business Partnership Over Garlic?

Let me start by saying that I am neither a vampire or anti-deliciousness. I had a work colleague who I got along smashingly with and we decided to partner for a project (we are both artists). Once we got into a less formal setting (art gallery vs workplace), he became more animated and excited about every conversation and would get close enough to me that I could almost taste his breath. I even scheduled our meet-up at 8am the last time, hoping for morning/coffee breath but it was distinctively garlic. I should have stated that we became friendly during covid but are in Texas so masks only helped delay the issue for a very short time. I have to admit that other things about his behavior kinda grossed me out (blowing nose in front of customers etc), so it was a pretty hard "I'm outta here" when i decided I had to either say something to him or just end our side project. I guess am i the butt hole for making an excuse and then ghosting him?
