The man will do everything to keep the girl he likes. He can even admit to her in love. But you still need to attach importance to what a man does, and does not say. And when a girl really likes him, he will do it, even through strength:
If a man falls in love, this girl becomes his number 1. He will do everything to make you happy and want to be with him.
Men have a natural instinct to protect their loved ones from threats. If he can not stand up for you, when someone insults you, he does not love you.
