Dumb question, Infidelity is wrong whether same sex or different sex and should be grounds for divorce.
The insane of s triangle, is worse than your head bring tangled in a dinner Bell
No, not homosexuality. But if in a relationship and it's infidelity...Then yes. Your question and the current law is silly.
Can homosexuals legally be married in DE? If so, I'm sure they're aware of it before their nuptials, so why divorce? Otherwise, stupid stupid question.
