Yup, divorce-busting is always a tightrope walk... I think you have figured that out already... its not fun in the short, term but it is rewarding.
At the VERY LEAST if you DO end up moving on and find someone else you will know HOW to LOVE by CHOICE and not just be following your impulses... 99% of people moving into a LT relationship and marriage just act on impulse. They love by impulse rather than by choice. And when the impulse is to act selfishly, they just revert to that instead... if you love by choice, there is no fallback.. you keep loving by choice every day for the rest of your life.. and its a great feeling.
