As a guy, I am deficient in writing about romance. But other than the writing, I have displayed some decent romance chops.
I have thrown multiple surprise parties for my wife. I have surprised her with romantic gifts. On one Valentine's day, I called her to the door as she was getting ready to go out. She was met by a barbershop quartet that serenaded her (I got to take their fee off my taxes, since they were a gift that I got from donating $60 to the local NPR affiliate--yeah, that part is not romantic).
Finally, on another Valentine's day, we dropped the kids at some friends' house and went out to eat. Over dinner she said, "This is so nice. I wish we did not have to go home."
I said, "We don't. I rented the honeymoon suite at the hotel across the street and dropped the kids' clothes and toothbrushes at the babysitter's earlier." And I really had.
But when my characters find love, it is usually a practical thing. Abe's family had died and so had these two women's husband. Jake Fox was forced to marry Aline Elliott by her father, Wiley. Wiley thought Jake was probably going to die and was hoping that Aline could inherit Jake's property. Bryton fell head over heels for Tonjan (literally), but she ended up rationally choosing the High Priest--but Tonjan is a Priestess of Aatar, and they are like that.
And on the horror side, one happily married couple is destroyed by her unfaithfulness--she chooses her past over her husband. And one husband has clearly invoked a power that has possessed him and will soon result in his killing his wife and child.
It is time I try to do a seriously romantic story.
