Best English-Speaking Country Which Legalized Gay Marriage?

Hi I'm from HK and I'm planning to spend my life in a legalized country, call me fairy princess but living in a city which doesn't allow, recognize gay marriage and even almost going to imeplement the "discrimination law" is not what my life was meant for. Most gays here have pessimistic attitude towards love as we can't marry, even if we married in other country, we won't be recognized as married in HK, we don't have residential rights, health-care rights, savings inheritance or even the rights to sign a surgery approval letter for our partner in case of emergency :(Comparing from UK, can you suggest some English-Speaking Country Which Legalized Gay Marriage that are easier to migarte to? Thank you
