A good point Madgran, the f.i.l. may well have thought about any possible ramifications had he not told them about the 'phone call. I agree that for the sake of a simple response from OP's D, this could have been avoided.
Hopefully the OP will be able to give some thought to her D's and s.i.l's perspective. Hard to do at the time if you're feeling cornered and what you believe are false allegations being made.
Egg shell walking just increases the levels of stress and anxiety not just for her but family too. As you say, it can be a very fine line between being overbearing and expressing love and concern, and not replying to 'phone messages for 4 days can simply exacerbate the problem.
No, I'm quite happy with the responses I've given, the way I've expressed them and my humanity Herefornow.
