Trying to reconnect with my ex slowly but he feels distant sometimes. Not sure what to do

Hi everyone. I could really use some outside perspective.

My ex and I broke up some time ago, but recently we started talking again. The conversations are usually friendly and sometimes even playful. We’ve talked about random things, sent each other TikToks, and even played games together a couple of times.

Sometimes he’s caring too. For example if I’m not feeling well he’ll say he hopes I get better or remind me to take care of myself. So there are moments where things feel comfortable and natural between us.

But other times he feels a bit distant. His replies can be short, and he doesn’t really start conversations himself. Most of the time I’m the one reaching out first. He also hasn’t added me back on any social media, which makes me wonder if he’s keeping some distance intentionally.

I’ll also notice that he might take a while to reply even if he’s online, though later he sometimes explains that he was tired or busy.

The thing is, I still care about him and I’m trying to reconnect slowly without putting pressure on him. I don’t want to rush anything or make things awkward, but I also don’t want to chase him if he’s not actually interested in rebuilding something.

But idk what is going on in his mind? What do u guys think?
