friends want a realtionship, girls i want relationship with want friendship

this seems to happen to me so often. I can't be the only person that this seems to happen to though? I'm not really the sort of person who dives straight into a relationship with someone they get to know, I prefer to become friends and really see how things are working between us.theres a lot of occasions where girls get to know me and are very impatient and want to push for a relationship, everytime this happens its always a girl who doesn't have what i'm looking for in terms of relationship and who cant satisfy my needs.so I prefer to stay friends with them, often we will become distant after this though.

it also happens the other way round. girls which i am attracted to and think could make good partners for me are not particularly interested and prefer to stay friends instead.
