There was a reason you got together to begin with, a seed of love that kept you going this long. If you still feel that love, it's worth working to find a way to communicate and get in sync with each other again. Many loving relationships get off track from time to time. It will take work to restore it, but it's worth the attempt if you know in your heart that you care about this person. Maybe you're the one who is on the verge of giving up on the relationship, but your partner wants to keep trying. If you've been together for a long time, it might be worth giving it your all to try to save it. It might be possible to see your partner's love for you and have faith that even though you're going through a rough time right now, things can get better. Weigh the options and see if it's worth it to you to try for the sake of your partner. No matter how good things used to be, or how much one party wants the relationship to keep going, sometimes it's clear that it has to end. If you've already put in effort trying to save the relationship, and you no longer feel love or the will to try to reignite it, it's OK not to force yourself to keep trying. Don't spend months or years dragging it out and criticizing yourself for not being able to make it work. It's OK to choose happiness over self-sacrifice. When one person stops participating in the relationship, it's better for both people if it ends. There's really no way to work on a relationship that's based on toxic patterns or abuse. No amount of working on communication techniques or trying to reignite the romance is going to make things better long-term. You may feel that you're getting something out of the relationship, but you have a lot more to gain by being free.

How would you rephrase that briefly using Vietnamese?
Hãy cố gắng cứu vãn khi bạn vẫn còn yêu. Cân nhắc về việc hàn gắn nếu “một nửa” của bạn muốn thế. Cho phép mình ngừng cố gắng nếu thấy đã đến lúc. Không cố gắng cứu vãn một mối quan hệ độc hại hoặc lạm dụng.
