My wife died almost two years ago. I know , different situations. The point is you can move on but only if you really want to. So she cheated on you. It makes you feel inferior. I get it. Do things to improve yourself. Things that will jack your confidence up. Then when you feel half way ready, grab the nearest pussy and have at it. After my wife died I felt like I was dieing. I started working out then I sought professional help. Alice Little is the number one sex worker in the US. She resides in Reno and you can find her online at the bunny ranch. We started with an email relationship and after some time I went to see her. One night with her will change your life. It goes beyond sex. Again, you can move on. Man up! Get back on the horse.
