Self-confident
I hope he is handsome, but I am more interested in him being happy with who he is. “Tall, dark and handsome” is much less important than “self-confident, content and happy.” If he is the latter, he will have a solid base from which he can grow his love for you.
If he is comfortable with himself in the purest of ways, if his self-confidence is not based on other’s opinions, he will be able to love you in ways that reach far beyond the “tall, dark and handsome” mannequin in the window.
