Joe, I notice that on another thread you stated that I seemed to be saying the same things that your friends were saying.
Maybe you are trying too hard, or maybe there is some little thing about you, that you are not aware of, that may be causing an obstacle to relationships.
May I suggest counselling.
A counsellor can give you feedback on your behaviour and personality and can give you advice on relationships.
You sound like a very pleasant person, who needs help from someone, who can talk to you honestly and pick up on anything that girls might find off-putting.
It may just be that you seem to be trying too hard and expecting others to try as hard as you do.
Life isn't that simple, though.
What do you think?
Good luck!
