Hi, DBR, welcome to the bored. The web site is "Divorce Busting", but from the description of your situation, I can tell you that you have come to the right place.
If I told you that having a spouse reject you on a regular basis is normal, would it make you feel better? Probably not, but you are in good company. I can't help you from personal experience. But I can tell you that it is good that you are trying to solve the problem now, because it can always go from once a month to never.
There are a ton of people on this bored who have made progress on their situations. Maybe if you elaborated on yours, they could give you the benefit of their experience.
SM
