I'm with YGirl. Since it's poly, there's no reason to drop the relationship. You're not limited to that one relationship, so you can make the most out of it and still live the rest of your life the way you would otherwise.
My marriage feels like an LDR a lot of the time, with my husband working out of town 10-on/4-off. Right now, he's working 10-14 hours away, and he makes the drive every other weekend. I'm not saying it's easy for him to spend that much driving, and it's hard for me to be on my own so much. He says he likes it because then he can just focus on working, get in some kind of "zone".
I guess it's quite a bit difference since he's coming home and not just visiting. I like to believe I keep a home worth coming home to
