Are you romantic?
I think it is hard when you have been with someone for a really long time to feel romantic towards them on a day to day basis. You may love them and feel close to them, but what about romance?
I used to be the type to leave love notes on a pillow or do sappy things like that. I don't know what happened, life or stress.... I just stopped.
In your relationship is there romance? Or do you think after having kids that just naturally fades away?
