I also found questionable messages and calls from this number on my husband's phone. He claims she's a charity worker - most likely offering free sex.

Caller: Christine

This number called my phone looking for my husband. When I asked what it was regarding, said they met at an event and he gave her the number. Seemed surprised to hear I was David's WIFE, said she didn't know he was married! Have spoken to others who've had similar shady experience, and have received inappropriate messages from this number aka Chrissie.
