Confused

I’m confused on what to actually do for a date. So I get like 6 matches a month and generally spend a few days just chatting about our bios and seeing if there’s a vibe (without it feeling like I’m forcing a conversation). But anytime I ask when the woman is free it’s always I’m not sure or I’ll let you know. I know that as the man it’s expected that I plan and pay for the dates which is fine but how do I even get to the date if I don’t know when she’s free? Should I just say let’s go out Friday at 8 for ice cream and a sunset walk? It could be that I don’t suggest dinner dates as I don’t know the person that well and don’t want either of us to feel obliged to stay for an hour if it’s not going well. Is it the dates themselves that are getting me ghosted? Or not being more forward about what date? I haven’t dated in 4 years and getting back into it has me feeling a little discouraged. I’m 25 if that matters. I like first dates where it’s easy to bail if it’s not going well think mini golf or arcade or ice cream as I said earlier in the post. I suspect it’s me not offering dinner dates but I’ve had bad experiences with them and would rather it be a 3rd or 4th date type thing
