A Whole New World

I(27F) recently dated someone(29M) for about a month. Right after the break up, I dove head-first into educating myself on attachment styles. I had an inkling that I had an anxious attachment style while we dated, but after learning more, I realized that he has a ton of dismissive-avoidant tendencies. The breakup followed a stressful event which resulted in him pulling away/avoiding me and it stressed me out too much, so I ended things(I also just don't think we were super compatible so ending things was for the best).

A couple of weeks after the breakup, I reached out wishing him well and apologizing for how things ended. I wasn't proud of how I did it and I was feeling guilty. He's a nice guy and I'm not trying to make enemies. To my surprise, he responded right away. We actually texted back and forth pretty consistently for about a week.

Yesterday, he told me he hasn't had the motivation to go back to the gym since we last went together(which was as a couple). I thought the natural thing was to offer to workout together but I also put in my text that I would understand if it would be too weird. He left me on read for about two days. When he responded, he made no mention of my offer. Just that he was sorry it took him forever to write back and then he started a new topic. It doesn't really bother me so I'm fine continuing a loose friendship with him. I just thought it was interesting.

Imo, he could have just told me he's not interested in hanging out or whatever the issue is, but maybe I'm being too hard on him?

Do you guys think this is him being dismissive-avoidant? Or did I make him uncomfortable and this is a normal reaction?
