Possibly bizarre.
But there you go, that is how it is.
I take my friendships very seriously as well, I don't pretend to be anything that I am not and I don't expect anyone else to.
My friends know who I am, I am a very uncomplicated type, as are they on the whole.
I don't really have any secrets, the work thing has never come up because DH has never asked about work and I have never asked about his, we are just not interested and we have both signed confidentiality clauses, we talk about work in the general sense but not in the specific.
Friends are different, there is overlap, he cares about the same people I care about, if it effects me then it effects him.
DH is socially adept, he is very unlikely to pass on any sort of secret I tell him, it isn't a concern because I don't know any and intend to keep it that way.
'Mate before Dates' was fine when we were 16, but he is a husband of 14 years and a mate of 20, I am not interested in my other relationships as I am in the same way.
That is how it is and it works for me/us so I really can't see any reason to change things.
