My husband doesn't realize and will not accept his brother in law is causing issues.

I don't condone my behavior in the least. But I will say that I warned him many times to give me back my laptop. I felt very triggered that he took my laptop and was trying to act like I was the one at fault. He got mad that I was trying to take my laptop back. I told him it's completely unacceptable that he's acting this way and he laughed that I was calling him unacceptable after what I'm doing. Basically all this pushed me to what I did. Again, I know I am wrong. But I'm providing context for my actions.
