Lucy, I for one thank you for your post. I don't think I would be doing my relationship any favors if the reason I commit to working at it is fear of the unknown. If I decide to stick with it, I need to acknowledge rationally the sacrifices I might need to make. It's like when you invest in a business, you have to know the value of lost opportunities in order to make responsible decisions.
I hope you keep posting and let us know how things proceed in a HD/HD relationship. Congratulations!
