I think my wife thinks I sleep closest to the bedroom door to keep her safe but chances are someone would break in through the window on her side.
Has this been a problematic subject you two have discussed?
That's the only thing she talks about these last few weeks
It's understandable that your wife thinks you would want to protect her. You should clarify any misunderstandings. This will help you both understand each other's perspectives.
I don't like to sometimes.
Communication is very key when it comes to relationships. If things do not get talked about then things do not get fixed. You need to put in time to work on your relationship, so even though you may not like to hopefully you choose to since you know it is important.
