Red flag? :-/

I've been seeing this guy "A" since the end of May. We're not in a relationship but we are exclusive and probably on the way to being officially in a relationship soon.

The past week has been really hard to me with family and work and health stuff and I got so depressed I slept for two days straight. He was really kind to me during that time and let me have the space I needed to recharge and get by. Today my friends told me to be ready at 12:15 because they were taking me for a socially-distanced self-care day. I told A the plan just to be courteous.

12:15 comes around and it's just my one (gay) male friend. He said that everyone agreed it would be safer if we weren't in a group in the car so he said we're postponing the group day and he was just gonna take me out and cheer me up. We went to a few outdoor markets and got lunch, but his car died when we were about to go to another market. There was nobody around but we were super close to where A lives, so I called him and asked if he could help jumpstart the car if I promised to buy him dinner tonight as thanks for his trouble.

He came, helped us out (this was his first time meeting my friend but I talk about him a lot because we're best friends), and then left. We made plans to connect when I get home.

Long story short my friends' car broke down for real a few blocks down the street so we called a tow truck and I waited with him for an hour until it arrived just in case. When I got home I called A to see what he was up to and if he wanted to connect. He sounded pissed off on the phone so I asked if he was ok. He said he was triggered and that he thought it was weird I said "a couple of friends" were coming but it was just my one friend. I assured him that my friend is as gay as the day is long and that nothing even remotely sketchy happened. I asked if he still wanted to see me and he said yes but he still sounded upset.

I still haven't gone over bc I'm kinda weirded out that he was "triggered" by me spending a self-care day with my best friend... I don't really want to continue seeing him if he's going to get like this every time something changes in my schedule or if he doesn't even trust me hanging out with gay men???
