I am so sorry that SIL is at this once again. It can be aggravating to have interfering ILs who think they know what's going on and can dole out some 'wisdom.'
Please ignore SIL's rant. H most likely fed ILs lies and more lies about his situation and laying the blame at your feet. The ILs don't know the entire truth and are only hearing H's side of the story which, as you can see, is all gloom and doom about the Court. IT is clear here that H feels really stung by the Court's outcome so he's spewing more venom about you to his family. It is funny to read that SIL is projecting from H that you're badmouthing him!!!
I-G-N-O-R-E messages from SIL. Do not contact H at all.
Hold up your head high and continue riding out on the high road. Continue conducting yourself with integrity and dignity.
