I don't think you can trust someone you have never met. Trust is something that is earned over time. That said, you have a somewhat good feel for this guy at this point so scheduling a 'date' seems reasonable. Meeting in the daytime for coffee in a public place is the usual way to proceed in the on-line dating world. Tell someone (not necessarily your family) when and where you are going for safety reasons. Keep the date short ... you are only getting a feel for whether you want to proceed at this point. And you may have some anxiety to deal with which is another good reason to keep the meeting brief.

Best wishes. I hope it turns out well for you.
