Taking a Break?

I’m so confused. Recently I’ve been having thoughts about how I’m not so compatible with the guy I was dating for about two months, and have known for over a year. He did absolutely nothing wrong, respected me and my wishes, and did everything to try and take care of me to get rid of the stress I have from work and school. There were a couple things that I started looking into that made me think that what we had wasn’t right, and it was causing me complete stress and anxiety. I would become anxious before going on dates and then when I was on them I’d be completely fine. But it felt like I was always anxious, and I think those thoughts took over, to a point where I just wanted to end things.

Last night, I sent him a message saying I needed to call him or talk to him in person. He called me back within a minute of me sending the text. He was surprised, (which I don’t blame him for- these feelings came on pretty quickly on my end), and he said he was going to accept my decision but of course he was going to fight hard for it. He said he would drive out to my house and we could talk in person at that late hour. When he got there, he was immediately hugging me, which I felt guilty for. He told me that he did not want to let me go and he knows that he got a “good one”. He understood where I was coming from in that I wasn’t ready for a relationship right now as I had previously thought I was ready. He tried comforting me, tried convincing me that we all have our hiccups, etc.

I still felt like an ass as I thought that was what I wanted, for us to take a break. I was/am just so overwhelmed that I felt I needed to “simplify” my life. He kept saying he didn’t want to let me go multiple times. He hugged multiple times, and I feel like shit still, even after. Part of me regrets what I did, what pain I caused him, and how it played out. But a part of me is wondering if I did make the right decision, and I just feel bad for him which is why I have so much regret, or I chose the wrong thing and overreacted?

He strongly urged me to think more and reconsider over this Thanksgiving time that I have off. What do I do? I feel terrible, and regretful, and mean.
