I'm no longer attracted to my wife
Why are you no longer attracted to her?
She's a stupid bitch and I hate her.
Clearly your marriage isn't a good one. It's rude to talk about your wife that way. If you really do hate her, you should either seek or counseling or a divorce lawyer.
You don't seem to understand what I'm doing. I'm going to text my wife that I hate her.
If you are that unhappy, you should probably get divorced. You aren't making her life better so you both shouldn't be miserable.
