How to justify second marriage?

So, what is it that you have to justify?

That you entered into a relationship and then, at some point, decided that you wanted out?

And who do you have to justify to?

I guess the need to justify can be aligned with forgiveness.  But who should you be forgiving and why.

If you enter into a relationship with the best of intentions and at some point it is not working out it stands to reason that you have to make a change.  Maybe the main question or challenge is to how you entered into the relationship to begin with; under what condiions, and why you chose to get married - for the second or third or ? time.

The question is around a second marriage.  This sounds like someone has gotton divorced for the first time and wants to get married a second time but needs a reason for the sake of someone else' opinion or approval.  So what is up with that?  Where is it written that you need someone else' approval, outside of the (in the case of marriage) other person?  And if you are trying to convince the person you want to marry that it is OK then maybe your questions is "how to justify a third marriage."

And if you need to justify a second marriage to yourself and not someone else then you have the answer: don't do it!

A second or third or any number that is in your future should happen becasue you want it to happen and not if you have to justify it.
