I would be depressed if my wife died and id have to be alone with our kids. knowing me, i wouldnt date other women for a long time but if i ever get "over it" i would date with someone because i dont want to live alone, even if my wife died...
I always wondered that question to this day...Always a split answer.
Main concern is the thought of never having you-know-what again...ALTHOUGH, is it really a problem if you're not getting married, but you're just getting it from ONS? :X
It depends on the love I had for them. My first thought is... no, I wouldn't. If you're married to someone... the assumption is that you, at some point or the other, wanted to spend your entire life with your partner. That's what vows are all about, after all.
If you were truly in love with them, there's nobody you'd rather be with, in life or death. That being said, if it was a relationship that started to fail on multiple levels, I could see someone wanting to get re-married.
