Maybe frame the talk in a way which sounds like you are looking out for him and doing him a favour.
By that I mean you could say like ‘wow you have a good girlfriend. But maybe don’t say ‘this’ or ‘that’ because women don’t like that. For your sake maybe stuff like ‘this’ instead’
I don’t know. I am pretty awful at important conversations
I would challenge him on it. If he doesn’t correct his behavior consider eliminating him as a friend. I try to only be friends with people who will lift me up.
I mean is he primarily your husbands friend?
If he is then there’s not much you can do about it.
But you can choose to avoid the guy as much as possible
