Why Are Gay/Lesbian Divorce Rate Higher Than Straight One?

I read an article saying gay and lesbian couples tends to separate more often. It also says marriages tends to last shorter and especially lesbians have a high divorce rate. Heterosexual couples tends to divorce much less frequently. I'm wondering why it's like that and if heterosexual marriages are better. Would it also be more effective not legalizing same-sex marriages? #Lgbt #Gay #GayMarriage

Look it up if you doesn't believe me.
