Hi, thanks so much for all the replies. I got back late last night from a great trip and found the mail.

Now I have't opened it. It comes from a specialist association that my husband has dealings with and I do not and never have. I also live in a different country from the association (my xh has a home there, and I do not). Sorry to be mysterious but I do not want to be identified.

Even if it is a marketing drive, I would not pop up on this data base. So it seems highly likely (nothing certain in this world except death - people seem to find ways around taxes LOL!) that they got teh address from my xh or someone close to him. I give it out to few people, and isn't easy to find.

I have had the house three years + and have never had a single piece of mail here for him until now, or at my previous address where I lived for three years also, while the divorce was going through - very occasional communication from him, but never, ever FOR him.

I am fairly sure he is still with OW2, and he has two homes of his own to get mail at, both of which he has owned for over 5 years, and which he can and does visit without OW (as well as with her)

The organisation that sent him the mail is one that he would have fairly regular contact with . . . . . and they sent it a high cost way, not normal surface mail, which is weird for a marketing drive . . . .and they are not a wealthy organisation. None of it makes sense, but I am curious, not obsessive.
