I like to think that marriage is like finding your favorite beer/wine/liquor....some people try Bud Light and nothing else, they love it and refuse to venture out and try new things. Others like to sample what else is being offered and then settle on a winner. Others have a favorite drink but every now and then feel like trying something new.

The deal is all of these will get you drunk, all will give you a headache, all will get you a hangover, but once you get one you like you'll always want more.

Just my view and of course it works on marital troubles too: some people like drinks that cause them to act like assholes, some people like drinks that always give them hangovers that make them wish they never drank that AGAIN, and some people over indulge in a specific thing and are then never able to enjoy it again (gin or tequila seem to do that).

Just my view.
