Do you frequently dream of other men while being in a committed relationship?

I have been waking up feeling so guilty because I have been dreaming about a bunch of other men and not my husband! I know that something is lacking in the relationship but I don’t know exactly what it is or how to fix it. I think things have just gotten a bit boring honestly. No intellectual conversations (when I talk I get virtually no interest or response), he never initiates sex anymore, same position boring sex when we do it, and just overall lack of what seems to be attraction and intimacy on both sides. When I have dressed up in lingerie or tried to be extra touchy feely and sexy, I get no reaction and feel rejected honestly. Seems like a downhill spiral. I now also don’t want to initiate sex or conversation due to being rejected all the time. Any advice from experienced married women on how to fix this?
