Our FB are on the same devices and we have many of the same friends, there has never been a problem about seeing each other's stuff.
For context, h works away a lot, and has cheated in the past twice that I know of, although I only recently found out, it was a very long time ago and I thought things were good in between (house, marriage, kids) so are trying to work through it.
A few weeks ago, he got a FB messenger from a Cathern Galvan. Noticed it a few days ago. No pic. Recently created messenger account, but doesn't have FB account. Apparently, his phone number was used to find him. He's had his current number for three years. Her message was 'hello bob' (obviously Bob isn't his real name).
He apparently doesn't know her. Convo was deleted. Nothing else so far. There were no baity clicks links as described in recent known messenger scams.
So, was it a scam, or a woman he doesn't want to admit to knowing? How would she have his phone number unless he'd given it out? Anyone had/ know of similar? The woman's name I gave was the real one used, in case anyone knows her and wants to get in touch :). Or has had the same random account contact them/ their dh.
