I've been with my fiancé for 2 years. We are in our late 30s. Our relationship was really good in the beginning, but now he has completely changed.
Recently he's done a few odd things and I'm not sure why. For example, I got some new food for the fish and put it next to the tank. The next day it was gone. I asked him where it was and he said he had no idea. Eventually I found it at the back of a kitchen cupboard. It's only us that live in the house, and it can only be him that moved it. He says he has no idea what I'm talking about, and says there's no logical reason why he would move it there.
This isn't the first strange thing to happen. But it's the first strange thing that I know he definitely did. It worries me that he is looking me in the eyes and lying.
He's been going through a very stressful time recently, but he's become very moody and critical of me. It almost feels controlling at times and like I am worried to speak my mind.
What's going on?
