First off chemistry can grow out of a friendship. If a relationship can't be a fridndship it will never be anything more.
Personally, "rejection" never did bother me because if I was TRULY HONEST with myself I always realized I agreed & it wasn't personal it was a real non-connection.
Wishful thinking relationships never work. You have things you expect in the other person in a relationship. If on a date & the other person doesn't fit what you are looking at, should she take that as a personal rejection or just that there isn't a match to the things YOU are looking for in a relationship.
Personally after a 33 year bad marriage I love my alone life & have no interest in ever dating or getting involved in any relationship ever again.
I hope you find a match....I learned after a bad marriage that it is better to know exactly what you want up front in a person & if any red flags are sensed....pay attention & don't go there. It is not rejection, it is wisdom that saves a lot of issues down the road
