My boyfriend is going to emigrate and go out to study. What should I do in the face of this situation? I'm so miserable and tangled.

As long as you really pay for your feelings, whether you can get married depends on the man. Don't be too entangled, delaying your career and life. Let nature take its course and handle normal relations. If he doesn't give up on you, you can go on naturally. Remember to be normal. Only you suffer.
