Why didn't your last relationship work.

So i just joined reddit to see what it is all about. Kinda still don't know how it works but what the heck.I'm curious to know why gay men's relationships fail more than they have succes. Are there statistics out there? Have people here on reddit talked thought about it. Is this perception i have even real? Is there a section around here that talks about this kinda stuff? If so please point me in de right direction.
