If you feel you are addicted, 1) permission to continue your addiction is not at all helpful, it is only enabling. 2) you are kidding yourself if you think you will be able to just stick to MPs. Guarantee you will escalate right back up to FS activities.
Either way, telling your SO/ asking for permission is not helpful and actually is a selfish to assuage your guilt, not to benefit or show more respect to her.
OK thank you for your input
