Should I (24f) text him (27m) or wait for him to text me?

I was casually seeing this guy from Hinge for 6 months. Both of us had reasons for being casual, but we connected on a deep level. Things in my life changed so I started wanting a more serious relationship. I knew he was still in the same place as before, so I ended it with him. He understood where I was coming from and it was an amicable “breakup,” but a sad one. He teared up a bit and hugged me several times. I cried a lot that first month because I was missing him so badly.

3 months later, I get a text from him asking to catch up. I replied and we got food/drinks this past Sunday afternoon, at a restaurant near my place (he didn’t want to make me drive to him). We were there for 2 hours, updating each other on our lives and joking/laughing a lot. It was a really nice time, though there were some interesting moments. We would stare into each other’s eyes when there was a pause in convo and he would bring up things we did/said in the past. He also asked me if I was still using Hinge and told me he hadn’t in a while, but then was like “where else do people connect.” Afterwards, he asked to hang more so we walked around for another hour (spent 3 hours total together) and that was when things really got interesting. He touched my arms/shoulders a lot and would put his arm around me for a second, gave me small compliments, and showed off a bit. There was one point where he talked about building his abs more and was like “you already knew I kinda had abs, you’ve seen them” and lifted his shirt up. He also basically asked me if his shirt looked good on him, in a kind of flirty way. He eventually started feeling tired so we walked back. We reached my street (he’d parked the next street over) and he asked if he could drive me home before deciding it made more sense to walk me. He came inside for a second to get a drink of water. After drinking some, he offered the glass to me to also drink from (we used to always share cups) but I said no. Before he left, I asked him why he’d texted me and he said he just woke up one morning and was really wondering about me. He asked if it was ok that he texted me and how I was feeling, asked if we could see each other again. I said he caught me off-guard but today was nice, we could hang again, and he hugged me goodbye.

Honestly, despite the weirder parts, I was feeling our meet-up was overall friendly because we split the bill and he didn’t do anything explicit. But then all my friends told me was definitely flirting with me and trying to gauge where he stood with me. The more I think about it, the more I think they’re right. A part of me is still attracted to him, so if he’s looking for a relationship, I’d be open depending on how the conversation went. But I’m thrown off by the fact he hasn’t reached out since. I didn’t expect him to start texting a lot, we didn’t even text much when we seeing each other since neither of us are big texters, but I imagine if he wanted more than pure friendship, I’d have heard from him by now. At the same time, he might be waiting for me to text him. I could see him thinking I didn’t mean it when I said we could see each other again, because I wasn’t actually sure myself if I meant it at the time and he’s an over-thinker. I think what I’m torn about is that I told him before I wanted more, I feel like if that’s also what he wants now, he should be the one to say something.

tldr; met with “ex” after 3 months of no contact last Sunday and he seemed interested in more than friendship. He hasn’t texted since and I’m not sure if I should just wait or reach out.
