He’s not interested. I don’t think it’s puzzling.

Why he still wants to invite you places could be because he doesn’t want to go alone. Wants a woman by his side. Like a wedding date. Or just wants casual encounters with occasional meetups.

If he was interested in more than that, you’d know. You never ever have to question or guess guy’s motives if he’s interested. There is never any doubt when they are interested.

“If he wanted, he would”. Don’t initiate and don’t sit and wait.
