I agree with gloombunny on this one. I am a bit woried about the type of relationship that you have found youself in dear. This seems to me to be unhealthy at best. If I may ask, why is it that you are not to leave the house? Has this always been part of your D/s relationship, or it this new?

I have a feeling that he is jsut looking for someone to take care of him, and not looking at this as a real relationship anymore, D/s or otherwise. Please talk to him and tell him how you feel, see what he says and please let us know that you are ok.
