Sure, it could be fixed, but it depends on you. Your ex-wife may never want to see you again after what you did to her. When someone is cheated on, it makes them feel completely worthless and unloved, disrespected and dishonored. You have to understand that this isn't always something that can be fixed, and that love in marriage is almost always conditional because of what can happen or be done by one partner to another. This is a lesson to be learned, as you know. You messed up big time; many people do. Make this a time in your life where you vow to never do what you did again, to anyone. When you love someone, faithfulness is easy. You have to understand that she may never forgive you, and eventually you may have to come to terms with that. I'm sorry that this situation is happening to you, but obviously we get what we ask for in life.
