If they haven't reached out, I personally would avoid contacting them first. You have no kids so that makes it easier
In my sitch, in contrast, my MIL contacted me a few months after BD right after she found out what happened from my XW as she was floored by it and was told untruths about why XW left me. My SIL caught up with me at the shops and we talked about it and she offered me her support. We keep in touch, and I visit MIL with S every few months.
Remember the principles here to keep DB with her friends and family if they do contact you, ok.
Just with the sms, remember to keep it brief and businesslike and just answer the Q, nothing more ie " Hi XW, I havent heard from them either. Regards Dan" That's all you need mate.
Cheers, DS
