Apparently my SIL's marriage is blowing up in a big way. We knew this was coming for years but I guess he moved out three weeks ago, which my MIL told us at Thanksgiving (SIL was elsewhere). DH has been texting with her a bit. Should I reach out separately to say sorry or something? We've never been close per se, but I also feel funny just ignoring it, because apparently she's really struggling. Or would it be inappropriate?
