In my own relationships, I know that I should break up with someone who doesn't encourage me to be strong and make my own choices and do what's best in my life, so if you're dating someone who doesn't want you to be the best person you can be, you shouldn't be dating them.
I think romance is friendship and attraction sort of meeting together and that does influence what I'm writing a lot. I try to establish the attraction, obviously, but I also think it's important to show the characters having actual conversations about things other than their feelings for each other - and to develop their friendship on the page.
