All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad is His slave and Messenger.
First of all, we ask Allah, the Almighty, to facilitate your affairs, relieve you of your distress, and reform your wife for you.
We advise you to continue seeking help from Allah, the Almighty, as He is the best to be asked and the best who answers supplications, and it is He Who answers the call of the distressed one and removes hardship.
Allah says (what means): {Is He [not best] Who responds to the desperate one when he calls upon Him and removes evil and makes you inheritors of the earth? Is there a deity with Allah? Little do you remember.} [Quran 27:62]
Abu Bakrah narrated that the Prophet said, "The supplication of the distressed is 'Allahumma rahmataka arju fala takilni ila nafsi tarfata 'ayn, wa aslih li sha'ni kullahu, laa ilaaha illa ant.' (O Allah, it is Your Mercy that I hope for, so do not leave me in charge of my affairs even for a blink of an eye and rectify for me all of my affairs. None has the right to be worshipped except You.) [Abu Daawood]
Problems occuring between the wife and her in-laws is an issue that is quite common, and the husband should be wise when dealing with them and endeavor to solve them with the help of rational and righteous people and those of whom it is expected that their intercession would be accepted.
In any case, your wife has no right to prevent you from inviting your family to your house, unless she owns the house, in which case she has the right to dispose of her property as she wills within the limits of Shariah, but she is forbidden from refraining to answer your call to bed, as we have already explained in fatwas 96046 and 88547.
If she insists on refusing to answer your call to bed, then she should be treated as a recalcitrant wife (Naashiz) in the manner clarified in fatwa 85402.
After that, if she becomes righteous, then praise be to Allah; otherwise, divorcing her may be better, especially given that you do not have children with her, as separation in this case is easier and its consequences are fewer.
The scholars stated that divorcing an ill-mannered wife is permissible without any dislike. Ibn Qudaamah when speaking about the categories of divorce, said, "The third [category] is permissible; which is when there is a need for it [divorce] due to the ill-conduct of the wife and her having bad marital relations with her husband and [the husband] being harmed by her and not getting the benefit expected from her [i.e. without fulfilling his need for sexual intercourse]…"
Abu Moosa narrated that the Prophet said, "There are three (kinds of people) whose supplications are not answered: (among them is) a man who does not divorce his wife despite her bad manners..." [Al-Bayhaqi]
Al-Munaawi said, "If he supplicates Allah against her, his supplication is not answered, because he is torturing himself by continuing to live with her."
Nonetheless, we advise you to make every effort to reconcile between the two of you and not hasten to divorce and let divorce be the last solution.
Allah knows best.
