A man who’s in love with be constantly smiling -- you may even notice that his eyes seem to be smiling at you, too.

He’ll make sure that you’re able to be a part of his future by planning things in accordance with you and making plans well ahead of time.
Scientists have studied functional magnetic resonance imaging scans of men’s brains when the men were shown photos of a person they love and photos of a person who they knew, but didn’t love. When shown the pictures of a person who they loved romantically, there was activity in the right ventral tegmental areadopamine and the right caudate nucleus.
