Give importance to your self-esteem as much as you value relationships. Never give up your self-esteem for anyone. Never let anyone understand your weaknesses or your weak points. Because once people recognize your weak point, they will hit you there.
Bigger than that, if the person you love is right and thinks you are the priority of his life, then there is no question.
Even then, if you see that the person is not giving you the same time as before. Not giving importance as before. Slowly moving away from you but don’t underestimate yourself repeatedly to stay close to him. Get yourself out of that relationship. Because it is better to pay everything than to neglect your love to the wrong people.
Don't let anyone play with your self-esteem and your feelings. Because you are much more expensive. Love yourself, live for yourself.
