If you beg someone to love you, you will beg for the rest of your life for his attention and affection. If you beg someone to be with you, you will have to beg all your life just so you can keep him.
Let love come out of free will, not out of force or pity. Even if you love or want the person so much, don’t loose your self esteem for it. Let them know how you feel and allow them to reciprocate freely and if they don’t? Yes it hurts so much, still let go and move on. Maybe it was never meant to be.
Keep an open mind, you never can tell what is ahead. You may even be grateful it never worked in the first place.
