I hope to read the end of this @khoola. But I would encourage you not to hurt your significant other by taking this further than this.
You need to get rid of this. Unless, you want to be one of those people you dreaded whenever you think about how they dump their families for the next one.
Feelings can't be controlled. Which means we can't control who we fall in love with. But most feelings do not need to be put into actions especially if it's going to hurt the people you care about. Don't give in to your hormones, it could be your undoing.
Going back to the reasons you love and married your wife and trying to pay attention to her again will help you get through this.
I am not saying this is going to be easy, but, I want you to know that you are strong and I believe you'll make the right decision.
