Go with how you feel. If you don't get good vibes from the guy, don't want to pursue the relationship further, then don't do something just to be "nice". Stay as honest with yourself as you can. If you all talk and have a nice time, etc. then go with that, share whatever of yourself you feel comfortable with. Just keep current with yourself instead of any ideas of the way things "should" be.

If you start asking yourself the "shoulds", should I let him kiss me, should I say/do something now, etc. then back up and find your heart again and let it tell you where you are and what you really want to say or do.

Notice how he treats himself as well as how he treats you. Does he take time to think before answering your questions about himself? Does he try to tell you how you should feel or what you should say? Does he put himself down in any way?

I always found it relaxing when my T was talking because that meant I could "rest" a little bit, didn't have to be on the spot :-) I think "observing" during a date can be restful too, instead of getting ahead of myself and wondering what I should say or do next.
