If that person is not born to express what he feels about you, do not beg him. Actions have to be born, but they have to be born at the initiative of the other, what you are going to sincerely ask you do not need, because if you have to beg, what is the case? It's not worth it, it doesn't make sense, so don't do it, love yourself.
Believe me, things have more value when they are born at the initiative of the other And not when they are trapped and have no other and if that person knows that he has to give you love and still does not do it, it is for a simple reason, that person does not love you. Don't ask him for something if he doesn't want to give it to you. And the most important; Don't ask him to stay, because that would be the worst mistake you can make.
Asking him to stay is like hugging a cactus full of thorns and the more you cling to it, the more it will hurt, so please, dedicate yourself to the greatest act of self-love you can dedicate.
Why do you want to be next to a person who does not agree with you? That you want to be happy but that person does not want that but that he thinks of himself? That is not love, love consists of loving each other, it is not enough just to promise, it is not enough just an intention, it is not just to please, It is a decision, to love no matter what happens around.
