Oh yeah.

You have to find one that doesnt want to repeat the cycle any more.

If you want to get mud on the turtle into your senior years you better be careful in evaluating the prospect and lucky that they dont hide better than you can detect.

I know lots that had a great relationship for years unwed, and after marriage it all rapidly went to shit.
You can never know all the factors but time is the best measure of honesty and character in a potential partner and evaluation of how that person is congruent to their rap..
