Does your husband live with you? That can make things very uncomfortable and it can be very hard to emotionally detach. One hard lesson I learned is that sometimes A have to "run their course." It's like a teenage couple. If you tell them they can't see each other, often that only pulls them closer together.
As difficult and uncomfortable as it sounds, sometimes you need to give space (and that includes emotionally protecting yourself and working toward detachment). Look at yourself and what will make you attractive to others (not just your husband). And then practice that on your husband. Try to look at it this way, if he wasn't your husband cheating on you, what would you do to try and attract him? You don't lose anything by "practicing" on him regardless of where the marriage goes.
Also, try to have to go out with friends and do fun things. When he's with OW plan fun things with friends, take photos and put them up around the house... start living an excellent life!!!
There is no arriving, ever. It is all a continual becoming.
