I'm lucky that my wife has an interest in pool too. She plays on my team and we do Scotch together.
You'd hate me if I told you how many nights a week I play.
In a marriage, it is a necessity that both of you have one common interest that you do together and also a necessity that you both have other hobbies
to get a bit of space away from each other.
If you can't have one night out for your hobby, then you have an underlying issue that you need to discuss with your wife.
What is the point of her sitting at home stewing over you being out one night or you caving in to her demands and staying home stewing over the fact that you are not allowed one night.
The end result is that it will hit a boiling point soon and it doesn't sound like it will be good if you don't talk about it now.
To me and others here, I can't see one logical reason that your wife would have that would justify her not letting you out.
You could cave in to her wishes and it won't take long before you become resentful. When that happens, you're done.
Better to be alone and have your freedom and piece of mind than live your life with regrets for how ever long it takes before you crack.
After all, Honey Badger don't give a Sht.
Here are some Badgers for you that will put a smile on your face.
