How should I no dat aguy is in love with me

The first sign of love is caring, as the one who loves is very interested in the one who loves her. Do not be unknown to his family, as he is proud of you in front of his surroundings. He offers you support and assistance when you need it and without asking for it. He seeks to formally associate with you and prolong the life of the relationship between you. His meeting with you is in public places, and he avoids meetings in isolated places. You are jealous if someone tries to get close to you, and his jealousy is natural and not superfluous.
