You cant rape your wife. That is the stupidest shit i have heard.
If a husband calls his wife to his bed and she refuses and causes him to sleep in anger, the angels will curse her till morning. [Sahih al-Bukhari, Book 59, Hadith 48
By the One in Whose Hand is the soul of Muhammad! No woman can fulfill her duty towards Allah until she fulfills her duty towards her husband. If he asks her (for intimacy) even if she is on her camel saddle, she should not refuse. [Sunan Ibn Majah, Vol. 3, Book 9, Hadith 1853]
When a man calls his wife for his need, then let her come, even if she is at the oven. [Jami` at-Tirmidhi, Book 12, Hadith 15.
If she is sick or on her period is not what were talking about. Its when she has ulterior motives to denying. Me personally i would just leave.
Ask yall parents because you seem to forget your religion and culture.
