Being partial to feet is not weird in any way. In fact many therapists consider them just as normal as many other partialisms. Many people like to engage in a good footjob, myself included. There is nothing weird or strange about that and if you think about it, a footjob is not a whole lot different than a handjob. But some spouses have an issue trying to resolve such a unique turn on and the best way to change that perception is through education. If the spouse was not told prior to the marriage about the partialism, or the expectations of it, things can be a little difficult to say the least. I would not give up on your wife or go to a provider since that would indeed be the equivalent of having an affair. What you can do, is try to educate her in a loving way that a foot fetish is harmless and enjoyable at the same time. There is an educational blog entitled Foot Fetish 101 run by someone I have run into on another forum. If you are interested in gaining access, Pm me and I will give you his contact info so you can subscribe to the blog and help educate your wife. There are many good articles there written by women who live with someone who has a foot partialism and they go a long way in trying to help other women become comfortable with the notion of feet in the bedroom...
