When times get tough, are you likely to stick it out or move on to the next best thing?

Life is short. When you experience significant relationship problems with your spouse/partner, how do you cope? What thoughts run through your head? Do you wonder if it’d be easier to leave and find a person you’re more compatible with? Or do you give it your best effort and hope all will work out in the end between the two of you? What happens when all your days become consumed by working on relationship issues and yet, nothing ever seems to get resolved? At what point would you say, enough is enough, and walk away?
