Hello and welcome!
A therapist told me that it is quite common for a spouse to be jealous in this way.
Certainly I can't approve of your partner reading your private emails, although I must admit my wife reads mine! But that's different. I allow her to, and she isn't jealous of my therapist.
Is it possible that your partner is scared that your therapist will encourage you to dissolve your partnership? That would be a serious and valid fear. I don't know what to do about that though. Reassurance might work, but she might not believe you.
Good luck!
