I don't believe it has to have anything to do with a god. One can decide to stand for their M, their vows, and not be a believer. I explicitly asked the judge presiding over our M to not mention God, yet I hold my vows sacred, and continue to stand by my W of 30 years. I hope you can accept this just as I accept your beliefs. Love.
M: A really long time. Crisis: 5 years. She's still worth it.
Life is never made unbearable by circumstances, but only by lack of meaning and purpose. -Viktor Frankl
