Along the lines of 'actions not words'--have sex and enjoy it.
As a BW, you may or may not be able to relate, but I'm frankly so sad to read how many people go through reconciliation, and particular where betrayed husbands are concerned--their wives were willing to give it up, sometimes with multiple men, and then they become (sorry for the strong perjorative language) frigid prudes around their loyal husbands who they supposedly want to win back.
I'm a woman and of course this can go both ways--that is something my husband and I had to work on as we reconciled (he betrayed me, albeit emotionally). I had expected him to want to have sex, and lots of it, once we were healing, but that turned out not to be the case, and boy was it painful (things are getting better).
Men really feel love through sex, it is something a lot of women need to learn. Of course, there is the issue of sex causing triggers for the husband, if his wife was physically unfaithful. But obviously having less sex is not the answer, and will ultimately cause any efforts at reconciliation to tank.
