The thing about romance and romantic movies is that they can be somewhat melodramatic. For a lot of actors there's a certain cringe factor that's involved with that.
I watched a lot of silent directors who were absolutely great like John Ford and Fritz Lang Tod Browning and also some very modern directors like The Coen Brothers. The directors take the freedom within their own movies to be melodramatic or funny when they chose to be. They do whatever they want and they don't care about the genre.
It's interesting - I always thought when I was doing more melodramatic stuff like 'Everwood' that the directors were constantly reeling me in and stopping me from being funny.
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.
