What should I do

I've been on 6 dates with this guy, I've known him since lockdown started but we only met up in August cause of social distancing etc. But he's not very talkative in person, I lead a lot of the conversation and it's really hard work. I don't feel there's much chemistry, even tho on the first date there was some, it's just gone downhill a bit cause he doesn't put much of an effort in when we're on a date. He's a very nice guy but I don't know if the dates are going to improve. Do you have any advice? Thanks!
