If you really love him, what would be happiness to him would be your happiness also.
Love is the condition in which the happiness of another person is essential to your own.
I love the ground under his feet, and the air over his head, and everything he touches and every word he says. I love all his looks, and all his actions and him entirely and all together.
Most people ask for happiness on condition. Happiness can be felt only if you don't set any conditions.
You deserve to be happy. You deserve to live a life you are excited about. Don't let others make you forget that.
