I think rather than always worrying and being hung-up on the trust thing, you need to keep in mind these things can and do happen (and can happen again!) so you always need to be strong and independent enough that if it does occur you know you'll make it through.

Sure it would be painful to go through again, but life can be painful. Anyone can die in a car accident tomorrow, or go through some other calmity. I think the main thing is to appreciate what is good now and those good things in the past, work through the hard stuff and just do the best you can. Have a life, friends, family and take the time to do the little things that bring contentment. Never depend on any one person to provide happiness (like spouses), but appreciate what they do bring... life always changes (for good and bad) and that's one thing you can trust!!!

There is no arriving, ever. It is all a continual becoming.
