You love your lover very much. He broke up suddenly. What should I do? We have been together for three years.

It's very simple. If you say that there is no reason to break up suddenly, the answer is that you have been together for a long time. You can choose to stay reasonably, and don't hesitate when you let go, but remember not to do excessive behavior and words and deal with it calmly. If she really invited you, if she really gave up, it's no use staying. It is better to wait for her choice quietly.
