I'll just say as someone who has read a decent amount of romance novels, I always knew that that is not reality. No real relationship is like that, What I will say is that for me I started reading them because my libido was gone (due to depression ) and I was looking for *anything* to spark it back up. My WH did nothing cause apparently he was off doing someone else the whole time.
My suggestion : if your wife is reading them, ask what she gets out of them. Maybe it's something you can share? I take the same stance on porn. I don't believe porn is bad. I think it can be a healthy part of any relationship. But you just have to ask what you're using it for. It's a tool. Just like all the other bedroom toys you may use.
