Ha! Good luck with that! I don't give too much power to anything that's going to put me in the negz. If it bothers me to much and it demands power, I give it enough power to have it go over a cliff. Wipe my hands and sayonara Baka negz.
Should you help someone who is reaching out and deeply-hurting? Absolutely. You should never have a relationship based on guilt over someone's poor choices. It is so easy to find ourselves in denial about someone's behavior because we so deeply wish they could escape their pain & suffering. But what we want for others doesn't work unless they want it for themselves. People must save themselves & you can only help a person who really wants it and is ready.
Addiction is NOT love. Addiction is a mechanism used to cope with pain and eventually can translate into infatuation. Love has characteristics and if your relationship does not have the character and integrity of those characteristics. "IT'S NOT LOVE".
