Since you think you may have seemed hesitant, I don’t see any harm in sending one light message. Something like ‘I had fun talking to you at the wedding, still up for that date?’ gives him a very easy opening. You don’t need a clever excuse when the interest was already discussed.

Texting is overrated af. A lot of bad texters are incredible in irl interactions and struggle finding people because there's much focus on it, not everyone want to be part of all that. It's not a good representation of how someones personality truly is. Their commitment to meeting up, keeping promises and making an effort going on dates and other irl activities is a great indicator tho

A bad texter who's interested will generally try to move to either calls, or physical dates, because that's where they can express themselves better, and feel like they can get to know you. It's kinda like when someone cancels a date. If they're actually interested, they'll try to re-schedule. If you want it to go anywhere, try to suggest something like that. If that doesn't work, does it matter if he's interested or not, if you're stuck in a situation where nothing happens anyway?
