The ruthless treatment of this help seeker is unacceptable. Imagine feeling you have the weight of two lives on your shoulders, looking for a way to mitigate the damage and being told: it's all your fault, so crash and burn.

Look person, people enter into the relationships that they want to. They live with the threat of being hurt because people are imperfect and each as human as one another. If you truly fear they will hurt thenself without you, you might also consider that you are not in healthy relationships regardless. Or even that you are not with healthy people.

You don't need to drop them or watch your life or theirs crash around you, but you can try considering the help, support, or structure they might need and weather the weight they place on you is healthy for you.

And don't nobody say I'm defending a cheater. If a girl came here asking "I think my boyfriend is maybe cheating on me?" I'd say something similar: consider the health of this trustless relationship.
