Why don't you cheat?

My fist love life experience I was cheated on out of nowhere and it was a shock and since then I hated the fact people cheat on their lovers, but after my recent relationship with a narcissist who didn’t know how to love and got me to understand why even people with a lot of morals contemplate it, because in that relationship the thought did cross my mind but my heroin addiction at the time stopped me because heroin became my mistress in that relationship.
