DS is 20, GF is just turned 18. They've been seeing each other about 6 months and seem very serious. Which is OK for DS at 20 I suppose, although it does seem to have happened very quickly.
As the 17/18 yo's mum I'd have had some concerns but her parents have been very welcoming to him, he's spent much more time at her house than here, has been away with their family and has stayed overnight there.
I'm happy to meet her, I do know her a bit, our paths crossed for a while years ago and she's perfectly nice. She's at pains in her text to say nothing wrong, but she thinks we should meet as we will both be seeing a lot of them (TBH I've hardly seen DS since they've been together and I'm trying hard not to mind!).
However, she's asked me not to tell them she's contacted me. I'm not at all happy with that. Face to face I'd tell her that, but by text there's no way to say it without causing offence is there?
