functional cobwebs

So many things have led up to this post. ok only 2 or 3.
1. I am listening to talk radio. love it. and there was someone speaking to military wives. The speaker said, "Whether you're living in an area for 2 weeks, 2 months, or 2 years, plant roots wherever you are. you'll be better for it." and i thought, I don't feel like my life is like a plant. I'm not going anywhere, i'm planted, but something keeps getting ripped out rather than tearing up my roots when I move.
2. I left a meeting for Side-by-side which is a group for medical wives (from med school to in practice for years)... we were preparing for a new year and feeling awesome in preparation, but I couldn't stop lingering on all the ladies who have moved over the years as they finish med school, residency, etc. Something is definitely being torn from my life while I'm staying planted.
and 3. as I put my girls in the car to go home that night, I ran into the STRONGEST spider web that has ever been made by a spider. I seriously think it pushed me back. and even the next day at a friends house, we found some on Nyla's carseat and it was visible and HARD to pull off. And as I looked like a maniac (imagine dance now) swiping, the last straw had been broken.
My life is like a cobweb.
You know you've seen them, many strings have been pulled down, but there are the few strong ones remaining that seem like they've been part of the wall forever and may never fall down. Things collect on the sticky wires... dust mainly. People don't even want to use their hands and touch that collection blowing in the invisible breeze. they go get a broom and smack at it until it sticks inevitably to the bristles.
So, is there such a thing as a functional cobweb?
I wonder if cobwebs were even made by spiders at one point or is it like dustbunnies. They aren't made by bunnies, they're just called that. Maybe a cobweb is made of dust... but that's the way i feel.
I feel like at one point in my life, I had this vibrant web. I felt comfortable and secure, and yes, occasionally a string would pop or even a couple, but I just built it back up. But now I feel a tidal wave of strings popping. People leaving for the greener grass and they've got me convinced that I missed something. I sometimes feel like I wasn't a good enough friend, or that we were good friends, but then .... I can't keep up with the dozens of ladies leaving. I had 7 leave from side-by-side this year... I have military ladies leaving. all in all, I feel torn, popped, and eventually abandoned.
And for those that stay, i go through tides of : what's the point?. I go through ebbs of: I am not as good a friend as _______. I have flows of: It would be better off if I just curl up....
again I ask, is there such a thing as functional cobwebs?
If this keeps happening that might just be what I become. I might be left to my own devices to collect dust and be left to be caught up by the broom because no one wants to touch that.
But i push on, building back up those broken web areas. I try to be a friend from afar.
And what if I move. What if one day, i'm called to go to Africa? Who will hold their spiderweb out to me across an ocean? Would I be gone for a year and no one prays for me, no one emails me because "out of sight, out of mind" then I would be a plant, uprooted and full of cobwebs... how odd... i think that's known as a fake plant... wait, I'm not fake.
so, I'll leave it one more time with : how can I be a functional cobweb?
