Move on man and find someone that wants you

There's like 20 million women in the UK between the ages of 16 and 65 and you are wasting your time on one that wants to be friends.
Fair enough they ain't all gonna want you but if you do the maths there must be at least a few thousand that would walk over broken glass for you.
Go find one of those to fall in love with and stop day dreaming about what might have been with someone you don't even know.
