Matt says: "OK, I need to just take a deep breath and stop reading into anything." Yes!
And don't read too much into your not being able to reach D14. Phones get lost, can't find the charger, etc. Assume the best and it is only 2 days, right? Don't just show up to W's place.
On the party, I would stay away, even if W's refrig installation conflict clears up. It is an awkward sitch anyway, as W's family will never treat you the same given the separation. Stay away, find some friends to hang out with, let W deal with d's getting to the party, if she wants them there.
Separate yourself from everything that is out of your control. Your W's relationship with her Dad sounds very weird. But you can't control it or have any influence on it. Perhaps the Serenity Prayer would help? Good luck.
