If I tell you I need you, do not take it lightly. I do everything I can to never depend on anyone, to never show weakness, and if I say that I need you, it means I am trusting you to catch me when I fall .
You will never have to question someone's interest if you pay attention to their effort. Effort speaks for it's self just as no effort speaks for it's self. When a person is interested in you they will let it be known.
