I appreciate the tips (really) but the gist of it sounds awfully close to "just treat them like a baby and pamper them". Could work if you _really_ need this person, but doesn't sound... healthy?
No. The point is to have clear boundaries. In fact, "treat them like a baby and pamper them" is quite the opposite of the advice
Don't offer to help them. If they ask for help, only agree if not expecting anything in return. Or be clear about what you'll want in return. Everyone is different: they may react negatively to rejection, which is it's own problem, others may not hold a grudge
Be straightforward: call them out on their behavior, preferably privately to avoid power games. Let them know the boundaries which if crossed you'll disengage from them over
