Life is messy they say. So true. Marriages can have an expiration date… it’s not meant to be prison. You are allowed to be happy, and so is everyone else involved. That been said; if you respect your wife, be honest and move on. Nobody wants to live a lie. The dishonesty is what hurts. She already knows it’s over. It’s up to you to man up. When you do, do right for your wife and family. Behave as you would want your daughter treated if she were to find herself in that predicament in her life; and all the pieces will fall in place. The truth has a tendency to do that. I’m sending you a Link to an article you might want to read here . It’s precisely about this situation.
I don’t know about the woman you are in love with but it’s possible that she’ll grow tired of your indecision. It sends a message about how much you truly love her. That could be a big turn off. Then you might lose it all. Just a thought. Life is short and I’m a romantic at heart, so I will wish you🍀!
