can someone have a fatal attraction and snap out of it ? can u trust after ?

we've all been there...tht one relationship tht was crazzzzzzy and nuts but it once was beautiful...some say sex complicates things, causes peple to go bat crazy. Breaking up is hard to do..but its apart of life, why complicate things an ruin a potential post relationship ? but wait, is it true some ppl lead ppl on because they like the drama an mess tht follows ? often ppl confuse lust with love an wonder why things go south, so again, can someone be trusted after a fatal attraction ? should we judge folks after a bad breakup when we knew nothing about wht happened behind closed doors ?
