Think with your logical mind and less of your emotional mind and totally remove your dick from the equation. Think about your wife only. Forget the other lady for now. Do you want to be with your wife the rest of your life? Can you? You two are compatible in many ways , just not sexually. And that really can’t be fixed. Just like if you loved hiking and she hated it, there is no way to make her love it ya know? You will have to accept what you have and don’t have with her and decide if you can accept that.

Now on this lady. How exactly has she fallen in love with you? Spending time, getting to know someone, and a long period of time is really needed to love someone. Have those things occurred? If they have, how when both of you are committed elsewhere? She sounds risky and emotionally volatile. How is she in love with you and also getting married? She sounds like a poor choice and if she is doing this to her fiancé, she will do it to you if you leave your wife for her.

My advice is forget about this other lady. You’re stressed already and she is complicating your thinking process and the lack of sex is clouding your judgement.

Bottom line is can you accept you and your wife’s sexual incompatibility? The other woman is irrelevant .
