Become a couple, fall in love for a while, and come together, but it takes time and effort to maintain it. The beauty that I could not cherish in the past is now so precious. If it was your fault that he left, then you should seriously reflect on yourself. The key to getting your relationship back is knowing how to solve the problem and how to make him fall in love with you again. Care about him more, communicate more, let him feel your love and warmth, so that he can return to you.
Avatar couple, it is not a simple thing for two people to be together. When you love each other, you have both sacrificed and been hurt. When you break up, you both need to face those unresolved issues again. But, you still held out hope because you still loved him. So, you have to keep working hard and keep trying to win his heart back. You don't need to make an eternal vow on your profile picture. As long as you are willing, the love you once had will still bloom in your heart.
