All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
The jurists stated that a wife is not obliged to reside with the relatives of her husband and that she has the right to live in a separate residence in order to be safe from any harm; for more benefit in this regard, please refer to Fatwa 84608.
Therefore, you have no right to force your wife to reside with your family. This also applies to her visiting them unless she agrees. The obedience of the wife to her husband is not an obligation except in regard to what is related to marriage and the matters pertaining to it; for more benefit, please refer to Fatwa 133365.
However, it is good if she visits them especially if you ask her to do so as long as she is not harmed by visiting them.
As regards your second question whether or not your wife is sinful if she neglects you, then you did not clarify to us what you exactly mean by her neglecting you so that we can give a ruling about it as we cannot give a ruling about something we do not know. In any case, if she neglects you regarding your rights upon her, then she is sinful otherwise no.
As regards you hating your sister-in-law and her husband due to the reason which you mentioned, then this is inappropriate and you have no right to do so as you are hating them because of something they have nothing to do with.
On the other hand, your wife should know the status of her husband and that his right comes in priority over the rights of others in case of discrepancy, including the rights of her parents; we have already clarified this in Fatwa 108161.
Finally, we advise you to be wise and try to solve the problem by firstly seeking the help of Allaah and then the help of rational people among the family of your wife.
Among the things which help enhance the stability of the marital life is that each spouse should know his rights and obligations towards the other and treat the other accordingly. For more benefit, please refer to Fataawa 85167 and 85308.
Allaah Knows best.
