IMHO, and I'm fairly new, as well, to Polyamory but this is what I think.
Long distance is hard for ANY relationship , be it mono or not, and the jealous woman out west may not take you seriously because you are the LDR. Are you attempting to communicate with your paramours?
If not, are their guidelines that the other women choose not to know about his other partners?
If so, be friendly but try not to be their best friends right away. Recently, I was taken aback by this and am currently working through some intense unease about it. Ease into the situation. The adage, "if you don't like it, too bad, get over it" isn't very correct when it comes to comforting paramours with the integration of a new leg.
All in all, I hope this helps and I'm not just speaking from the top of my potato box.
It's just me, my ramblings and the elevator music in my head.
