Sometimes I hear men and women describe their spouse as their best friend. Other times, they state their best friend is someone other than their spouse.
My husband is not my best friend (sad).
So, is your spouse your best friend (or gf/bf if you are not married)
Hmmm...
I'll offer you this much in reply. Upon nearly 25 years of consistent marriage to the one and only gal I've ever called my wife, she is, at this moment, my BFF. It kinda goes like this over time...I've always loved her daily, but there are times I don't like her as much as that love should suggest.
Marriage is a complex, challenging, and sometimes irritating situation. Just like a best friend might present.
Or even a dog,
What lasts and matters most, is an unequivocal and accepting trust of whatever your partner shares with you.
An often moral dilemma is said to question whether or not, if both are within a life boat, and both wife and mother fell into the sea at the same time, and only one can be saved...who would you save?
My wife. Without batting an eye. Of course I would mourn the loss of my mother (or just my best friend of the day), but the suggestion itself evades the lasting moral question. A question only you can answer honestly.
Fortunately for me, "religion" is simply not a factor.
