I would say date other women, it will boost your confidence & self-esteem, reclaim your individuality, go through the process of looking good again, getting ready to meet other women, improving communication, and looking at all of this as an outside observer during the process. You will gain alot of self-confidence during this process: you will look & feel different afterwards because of it.
Hold on....i can date? wouldnt that ratchet things up a bit around the house? my wife would believe that im just dating and not having sex?
What she believes is up to her, you aren't supposed to fill in the details, if she finds out your dating so be it but you don't have to let her know who, where you're going, the color of the gitch you're wearing, etc.
