Nothing says love like being open to having children with someone.
Just think about it for a minute.
A person who is willing to conceive a child with their partner is saying with their whole body, "I'm willing to have a child with you. That means I love everything about you so much that I want another person to exist who is like you. I want to see your eyes and your smile in my child. I want someone who walks like you, talks like you, makes decisions like you. I want to help create someone who's made in your image." That's pretty darn romantic.
Conceiving a new life also is a profound commitment to doing whatever it takes so that this new, unique "image" of their beloved flourishes in the world. When partners commit to having a child, they are signing up for a lot of self-sacrifice, which is the heart of real love. Blessed John Paul II describes love as desiring and acting towards the good of another human being. Parents have to do this constantly, from the moment they know their child exists. Babies are hard work. Little Children are hard work. Teenagers are hard work. Even adult children are hard work sometimes.
However, all of this work is completely worth it, because you're nurturing in your child the good you see in your spouse. A person who has a child with someone is signing up for a lifetime commitment to putting their needs second to their children's needs, and to working with their partner to build a life for themselves and their children. That's not just pretty romantic, that's swooningly, deliciously, heart-breakingly, wonderfully romantic.
