All anyone can promise is to be honest.
Just the idea that you can promise to always feel a certain way no matter what life throws at you for the the rest of your life is insane. You cant really choose your feelings.
AIBU to think that the only vow should be:
"I will always be honest [with you about how I feel]"
and maybe a second one of
"I will not get angry with you for being honest"
I have been to lots of weddings that wildly promise feelings of forever and always. But then again I've never married so am not really qualified!
Mnetters experienced in love and war - AIBU?
