I too chose "other" because none of the above fit.
I married at age 18 and was in that abusive situation for 7 years. When I divorced him, I had no plans on ever marrying again.
4 years later I married my current hubby. It took him 3 years to convince me to marry him. He's basically a decent man, and I have no intention of leaving him, yet we don't have anything like the marriage that I'd wish for. He's an over the road semi driver, so is home only a day each week. We're not close or intimate, even though we have 2 children and 24 yrs together as our history. I feel we're more a business partnership than married, but since I have no interest in ever remarrying and don't want to tear our family apart, I choose to stay where we're at and so does he. Actually, he won't admit there's anything wrong with what we are... so who am I to shatter his denial?
