Why is dating in the gay community complicated?

Basically, you are a guy in love with another guy who is in love with a third guy and none of you like each other.You end up fucking one of these guys (if you’re lucky) eventually because, sex. But then you leave the next morning and never contact any of these guys again.Or maybe you do, but the other guy decides to ghost you.Or you’re extremely lucky and end up dating a guy for some time until he gets bored of you and decides to open the relationship, which eventually ends because your partner falls in love with one of his fuck buddies.Why?
