Hey Complex, it's nice that her Mum has texted you. Sounds like, even if she doesn't know - she's concerned something may be up. I don't think she would have texted saying HVD if she 'knew.'
You could always let your W know you've had a couple of texts from her Mum & you just want to know what she knows before you respond. Your W may have told her you're having some problems, but not about OP for example.
