Because what else could we end this list with? It's the uppermost need of all human beings to be loved, and to have someone to love. It's the single most powerful, most rewarding and most risky thing we can ever receive or give, and every time we give it, we also give a little of ourselves along with it.
Men need you to love them like you wouldn't believe. You could tick off every other point on this list, but if you don't have love for him throughout all of it, he isn't going to feel it. Men absolutely know when someone's in love with them, and when actions come from a place of love. If you love him, embrace that feeling and let him know it every day of his life. Love without fear of loss and live without fear of love.
