I have a wife who has a psychic problem; she does not fulfill my rights as a husband. I married another wife to serve me and my sons, and I spend days with them equally. However, my first wife along with her sons sleep in one room and leave me to sleep alone in her room; would I be committing a sin if I do not stay with her since she neglects me?
If the situation is as you mentioned, that you spend days with both your wives equally, (Part No. 19; Page No. 184) but she refuses to sleep with you in her room and leaves you alone there, you are not a sinner. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
