This is called: Codependency addiction.
They need professional help.
You cannot save these folks from themselves.
Pay attention to people who call themselves your friends - when they try to rain on your joyful experiences & seem to be happier when you were bummed out/depressed & depended on them. Some people only want to be your friends when you're not faring well & they can feel like they're your 'hero'. If those folks were true friends - they'd help build you up so strong, you can stand on your own. If people like the described above are not happy for you - when you're less depressed & feeling more joyous, less dependent on anyone - it's a red flag that they weren't fully genuine friends at all but had hidden/unspoken intentions & they're unhappy when you're happier.
I don't believe in 50/50. I believe in 100/100. Each person steps into companionship, with their full hearted/full spirited/full soul selves & gives 100%. I do not love in halves. I only love in full. I don't want myself or my beloved to fall into each other so much that we lose our own selves along the way. It's so important for me that both people stay who they are, passionately; just allow the mutual loving companionship to nurture & complement the union but not toxify it with dysfunctional dependency. A free spirited mutual love, so genuine, that you never feel caged but feel free, yet anchored at the same time ππ
