Dear Annie: I have had a few health issues recently. During tests, my doctor incidentally found a mass on my spleen. I asked my husband not to tell anyone, except our kids who are 24 and 33.
I found out he told the neighbor down the street. I am upset. I haven’t said anything yet to the rest of my family or friends. He argued (yes, argued) that I didn’t say that and that I had said not to tell the family. I explained to him that he betrayed my trust. It was my story to tell when I was ready. He became belligerent and argued with me some more. I was still keeping my composure and said, “Even if I said I don’t want you saying anything to our families about it, wouldn’t it be implied that I certainly didn’t want my neighbors knowing?”
At this point, we are in a big argument. I told him I was going to remove him from my next of kin and anything else that would allow him to know my business since he has some issues with keeping my business out of his mouth (and I did, by the way). He told me I was the untrustworthy one. Again, still trying to have an adult conversation, I asked him to give me examples. He couldn’t and was deflecting.
We’ve had similar issues in the past where I think, “Gee, we are having an adult conversation -- a give-and-take, compromising, coming-to-an-agreement conversation” -- only to find out I was the only one present in the adult conversation and he’s gone against everything we agreed to. I am married to a man-child. He literally argues, “I know you are, but what am I?”
As of now, I have decided to keep my health issues to myself. Apparently, I am in this by myself, and his intentions are to seek sympathy for himself (I have suspected for some time he has narcissistic tendencies). I have so much going on, on top of everyday life. I just don’t have it in me to include him anymore.
