You are so right. And I'll take it a step further. When one or the other of you experiences a serious illness or accident and is changed physically or mentally forever that long-term commitment is what carries you through days and weeks and months of difficulty. MyDH became disabled at 47 with lung disease 6 years ago and can no longer work. He was in the prime of his life. Now he struggles to breathe just bringing the laundry up from the basement. His hair is thinning, his muscles are wasting, his thinking is muddied due to medication. He wears oxygen at night(mmm, sexy...NOT.) We're still relatively young and yet we have to face the havoc illness has wreaked on our lives. You'd think after 6 years we'd be used to it, and to some degree we are. But sometimes disability just reaches out and slaps us in the mouth and we're forced to face it all over again. Commitment, respect, and deep long-term love gives us both the comfort and staying power to stick it out no matter what.
I'll take a kind, respectful, funny man with thinning hair and a nasty wheezing cough over a hunky but insensitive stud any day.
