The mysetric puzzle!

I'm back to my confusion phase,this time not because of my own issues ,but because of other's.It's amazing how guys can keep girls in the clouds of doubt.I don't understand why???why when they are committed to somebody else,they approach other girls and act so innocent?why they then confess that they were strictly in a relationship and that they their relation turns out to be kinda on-an-off!!!So when they see some evidence of break up they approach and once again they challenge their chances,and when everything s back to normal they think they are better off with the EX???Can some body elucidate that for me please 'cuz I'm extremley astonished by how tricky they act ,and...
Anyways,I'm seriously sick and tired of analyzing every single situation,I'm fed up.I've reached a point that I no longer care about what's going to happen,I will never ever again ...(I don wanna share everything in here!!!),but anyhow ,I guess it doesn't matter anymore.Maybe one day...who knows...
