3. He makes too little effort to impress you
Men behave like peacocks when they want to impress someone. They spread out their tails and show how gorgeous and nice they are. If the man whom you love does not do anything to make impression on you, it means that he does not need you in his life. On the other hand, when a guy starts exercising, dieting, dressing elegantly and making other positive changes for you, it means he wants to be noticed by you.
