It's a shame that STBXW can't get over whatever has made her so avoiding for the kids sake. These are important times for them and it seems like such a small thing to do for their benefit.
Have you tried to talk to her about this at all? I guess that could be difficult with all she's doing to avoid you at all costs. But maybe if you keep trying, she'll eventually see the light.
Has her lawyer ever responded to your last proposal? Just wondering if you're still at a standstill...
