DH's brother and his wife have announced a trial separation. They have 4 DCs and various problems so all very stressful. BIL has told DH via text but says he doesn't want to talk about it.
For context, they were already together when I met DH over 10 years ago, so as far I was concerned they were equally part of the family. We don't live close and only see each other maybe twice a year, but I have always got on well with SIL, when we see each other we talk a lot about family stuff like how difficult MIL is, ie not just superficial. I get on perfectly fine with BIL, though our relationship has never really moved on beyond small talk.
I am quite worried about SIL. She isn't close to her family and I don't know if she has much of a local support network. WIBU to send her a supportive text? I sort of want her to know she still has an ally in the family.
DH says it's fine but I suspect if MIL finds out I will be accused of taking SIL's side. I'm not on anyone's side, it is a tough situation all round - I just feel that SIL has less support and anyway BIL would not really be comfortable with an emotive message from me. But I don't want to make a bad situation worse by causing a fallout with MIL.
