Am I not showing enough interest in this guy?

have been dating a guy off of a dating app, he’s a few years older. We meet once a week or so. I’m very in-experienced with dating so I’m not sure beyond some high school "relationship”. On our first few dates we didn’t even flirt or hold hands. We acted like friends. But we really got comfortable with each other I think at least.

Then randomly on a more recent time he leans in and then hesitated but then decided to go for it and kiss me. He missed my lips. And then we just didn’t really address that or try again. But we do hug, he stays in the hug longer and he holds tighter if it makes sense.

the most recent time I saw him he put his arms around me and held tighter but got a bit quiet. And I didn’t read the moment so I talked a bit. I think he was gonna try to maybe kiss then? And then when we hugged goodbye he looked like he wanted to go in for the kiss but I did it this time. I don’t know how to kiss honestly, I barely did it for long. Maybe I have to learn. What else can I do? He seems to be respectful but I think I have to show him more because it might look like I’m complacent?

We have seen each other for a bit over a month now. I still have my profile on the dating app and so does he but I’m not seeing anyone else so I think it’s time to discuss this maybe. My friend is getting married so I won’t be in our area for a few weeks soon. I am not sure how that’ll play into things. I told him about the wedding

Both in our 20s
