This isn't your typical home wrecking clip because you and I have to acknowledge the truth about this. You don't deserve her or any wife, girlfriend, or otherwise and you're an absolutely shitty husband and partner. Always have been and always will be. If she wants a divorce, suggest it and give it to her. I can barely stand you so I feel especially sorry for her! But you know what would make you a better partner? Maybe then you won't have to divorce and everyone can get what they want. Encourage her to seek out another man. Encourage her to cheat. She deserves so much better than you I'll tell you how.
