Something DH let slip a few days ago made me think that he had been in touch with his famous ex. Today I snooped and sure enough there was an email from her about sponsoring a young person etc, but making it clear that they had spoken (not clear whether over the phone or personally). Her message was friendly but nothing else, and she referred to him as a friend on an attached message to the young person. He hasn't replied so I have no idea how he's approaching the contact.
In the past, I got very angry when I found out that he had approached her to get guest speakers for an event, as he's got lots of contacts still, but probably none that are in the peak of their career / fame as she is at the moment.
I am angry. I haven't said anything. Reasonable or unreasonable? Confronting him won't change his behaviour as we've been there before and he's obviously gone and done it again...
