Did I hurt him or is this a slow fade out?

Confused.. did I really hurt him or is it a fade out.

I met someone on bumble, We are both 30. The connection, chemistry, attraction was super strong. We hit it off. We saw each other 2 a week and then once a week for three months. Covid has been weird, I never really attempted the casual thing but we both are super busy. ( he is in med school, I’m finishing up nursing and all my other things)

At 3 months I had a temperature check to see what we are doing and I didn’t know how to think about casual but at the time (I was open to a relationship but I’m not adamant on being in one). I tried to end it but we just naturally gravitated back.. We continued since we both didn’t know how we felt. (I am fully aware and what I’ve put myself in) We just knew we enjoyed one another time, and like each other. And given we both had a lot on our plates. I’m not needy and i there was him ample of space for both of us. It was nice at first.

5 months in we got into an argument, we tried to end it again but again….. we just naturally went back to before.

Fast forward November: there was a sudden shift. We were communicating more, flirty, talking, etc…. there was a catalyst that made me overthink.. my friends all questioning what the hell am I doing.. (Of course I’m overthinking now). We met up after thanksgiving and we had a very mature conversation. I told him how I felt. I said I think this is where I’m developing feelings. I know I cut him off at some points of the convo. ( I’m working on being a better communicator) but over all I told him how I felt now, and I don’t like being a transaction. We both agreed that we saw other people over the long time line of break ups.

A well after that I called him and he said he doesn’t want to talk, asked for space due to something I said didn’t sit well with him and he felt hurt.

I told him respected his space and in the mean time for him to think about what he wanted because I’m not lying to myself anymore and I want to explore this that we have.

My question: it’s been a month. How should I feel about this? We both are very honest people, I’ve been very transparent with him and I believe he has.
