Balancing Act

Why are relationships (and I use that term to encompass all variations and romantic forms) always so hard, sometimes I think I am better off staying single.  Getting interest is one thing, sustaining it is a completely different thing. Then there is always the balance of who like the other more.  There in lies the problem...its near impossible to find that relative balance.  If the guy likes you more, you want nothing to do with him.  If you like him more, chances are he's not showing the interest....hence why you continue the chase.  And of course you have to factor in timing to...someone should get all of these variables together and send them off to a mathematician and have them figure it all out for me.  Because I sure as hell waste too much time thinking about it!
