You have some good instincts. Keep listening to them. Never, ever get in a vehicle - whether it's your or his - with a man you haven't met before. If you're going to dinner together, on the first meeting, you meet him at the restaurant. You get there in your car, and he gets there however he will. You tell him that you have an appointment after dinner to babysit your sister's kids, or check on your aunt who is in the hospital - so you have an exit strategy. This is not deceit. This is maintaining appropriate boundaries. What you are actually doing after the date is none of his business. Simply say, "I have a personal matter to attend to." if you don't like creating a slight fiction. This first date should be a simple "meet-and-greet." After it is over, you decide whether you ever want to be around this guy again. You may not, or he may decide he doesn't dig you. You don't give him your address. Not yet.

If during the dinner you get scared of him, you say, "Excuse me, while I visit the ladies' room." Then you duck out the door and get into your car, or into a cab, and leave. Always have sufficient taxi fare whenever you go anywhere with a man you don't know well.

There are some very nice men who use on-line dating sites. Creeps and, even, ax murderers also use those sites. You have no idea who you are dealing with, until after you've spent some time in his company.
