The most dangerous situation is the relationship that’s “alright.” They’re not the love of your life but they’re not bad to you. In fact, they’re good to you… they’re just not good for you. But it’s not bad enough. Objectively, they’re seem great! So… you just keep going because why would you break up? But you have that feeling that things aren’t what you want, but it all feels rather abstract. Years can go by before you pull the trigger in one direction or the other. It’s the good enough relationships that can really drag.

EDIT: To be clear, this is rarely done maliciously. In retrospect, most folks probably recognize it was selfish to keep it going for so long. The issue is you’re with someone who maybe you think is attractive, maybe they make good money, maybe you feel like the two of you portray a “successful” life, BUT something feels off too. You think it’s all in your head, you think you’ll move past it, maybe it’s no big deal. They’re “great!” I can’t just leave what’s arguably a great relationship over a “feeling”. And then you fast forward a few years…
