Why is this so hard .

I think I'm getting somewhere with detaching,180,gal then I just hit rock bottom and feel like giving up .

What triggers it is the limited interactions that my kids have with W . And how they normally end up with them getting upset at the way W speaks to them or sometimes due to lack of contact either through text/Facebook etc.

I understand from MIL that W is missing the kids so much , but then can't understand her lack of contact .
Wondering if the W is having some sort of breakdown or suffering from depression and it's killing me that I can't help her .
