After reading everything and most of the comments. I have one thing that you need to do. Tell your wife. Your wife is everything you have. She made your children, she makes your house a home and she dedicated herself to you for the rest of her life. She loves you, hell she went through 4 miserable pregnancies for you. She DESERVES to know. If you truly are sorry, then just do whatever you can to make her believe you will never do this again. The problem is that you didn't just do this once, you kept going back. You didn't learn the first time. You need to learn, now. I personally would not be able to forgive you if I was your wife. Betrayal is such a devastating thing for me to wrap my brain around...but maybe she can forgive you. If she does forgive you, you can't just go on with your life as normal. You have to make her believe you love her and are sorry, you can't just say it. Actions speak louder than words. She is constantly going to be paranoid for a long time after you tell her, so be open with her about your day, do things for her that take lots of time. Do things for her that someone who didn't love her wouldn't do. Second thing you need to do is ditch the girl. Fire her first of all, and secondly tell her you're sorry but this whole thing was a huge mistake, you don't love her. You love your wife, and you love your family, and you would do anything for them. Shes just a hoe. She will pitch a fit like every teenage girl does, ignore it. She has a lot of loose also if this gets out, so she probably will try to hide it from adults. Most importantly, pull yourself together! We still have instincts, and yours need to be protect and love your family and your wife! You can't have eyes for anyone else, and if you do, shut that shit down! YOU have control over your actions and no one else. Put your foot down and resist the weakness that is your urges! Good luck. You have to give this your all in every way, dedicating yourself to proving to your wife that you love her and only her, and that this will never happen again. Secondly you have to give it your all to get your priorities straight. Good luck. Would love to hear an update!
