I'm in lust with my friend...

So there is a friend that I have...  whom I knew the the day I met him we'd be in trouble if we were ever left alone.... Hes literally is the first man that ever disarmed me with his words... we have be ever so careful... I'm also in a weird place with my boyfriend..... we are nearing the end of it all.... should I take the chance with my friend if my and my mister end it all???
