He will love you passionately and with all his heart when he loves you. If Aries chooses you, it is because she believes that she will be willing to give you the best of her. Once you enter their heart, it is not to leave so that no one else enters. She will only have eyes for you and no one else. But it will also ask you that all this fidelity and loyalty be reciprocal. For her, that is the most crucial thing in a relationship.
