Three years of love, and a daughter, three and a half months after breaking up, I dreamed that she came back twice last night, hehe, I wish everything all the best.

Dreams come from the heart, just because you miss her so much that you can't let her go. In fact, you know the specific situation better than anyone here, and you just want to seek comfort. If you really can't let go, then try to save it. If you can't do it, accept it. Life is like this. Sadness is inevitable. Maybe only time can untie you.
