Dear Smile Jewel,
I hope you are feeling better and know that you are loved!
Break-ups are terrible and heart-breaking, no doubt about that. If I have to give you a sincere and friendly advice, then I would say if the other person is not interested to continue this relationship, then it is better to leave this relationship here so that your self-respect is not hurt anymore. If the breakup happened due to a mistake of yours or you unintentionally hurt the other person, then it is best to apologize and try to get your love back. There is no shame in accepting your mistake and reconciling, 🙂
