Kali, Patchos, and wildmann have offered some really good options. I'm not sure what "your lady" implies (wife, common law partner, commitment??) If any of these, you've committed yourself to her and "just moving on" is not as easy as it sounds.
My husband of 20 plus years is 5x5...we have been using, toys (dildos, vibrators, buzzers,) porn vids, role play for years... Just recently we started with reality fantasies (read my blog for more info). Works for some, for us, our sex is off the charts. For others it helps them face some harsh facts about themselves. (They never really loved one another to begin with.) This way you can BOTH agree that moving on is best instead of one person making the decision unilaterally.
Hopefully, the former will work for you, too.
