If I get rejected in a bar after approaching a girl, it doesn't bother me. They don't know me.

However, if I take a girl on 1/2/3 dates and get a rejection, it hurts. She's got to know me and spent time with me, yet isn't interested. That's a clear rejection of me as a person. How do I get past this?

The dates I go on seem great to me. Lot's of conversation, fun, laughter, kino. The last 2 girls I dated, I kissed on the 1st date for one girl, and kissed on the 2nd for another. Some sort of attraction must be there to get the kiss and get more than one date? Yet when I try and arrange a further date (date 3), I get no reply and they bin me off! I really can't see where I'm going wrong and the rejection is tough to take.
