Trying to figure out Libra thinking

Starting with, the dating is over, and that’s fine. I’m just trying to understand his mentality. Was dating a libra guy briefly. I felt like I was always being critiqued. We recently went out with a large group for the first time.Totally fine he was hanging with other people since that was the whole purpose, but he was way less affectionate and it seemed like he may have been avoiding me. We ended up arguing at the end of the night and I said something on the aggressive side out of frustration and being in a shitty mood. According to him, he doesn’t want to date anymore because of that and because I moved my body away from him when he finally did make an attempt at some form of affection.

The thing that I’m trying to understand is how is something (that I see) so little, be such a big deal. I wasn’t happy with how he treated me and felt very disrespected all night long, but I viewed it as let’s have a discussion and figure it out. He hadn’t even realized I was upset during that time.
