So I agree with May that the WW does not have to beg the LBS for another chance but they do have to see the WW as a person of value, life with them is better then life alone or with someone else and they need to work to get them back. Without this he will likely walk again down the road.
I also agree that the WW does not have to be a sociopath. If the WW is not a sociopath then they typically have a lot of resentment built up and the affair is an act of anger. So if your husband is having affairs due to resentment then it is going to take a really long time to burn through it. Are you 180ing the areas that made him resentful?
I will also give you my opinion that your husband is not confused he’s scared. He wants to date other women but he’s afraid of the consequences if it doesn’t work out for him. Don’t confuse confused with fear.
Still think if you DB your butt off you have a chance. He’s got one foot out the door not two.
