Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
Firstly, if you are fulfilling your wife's rights then her threatening you with separation has no basis and such a separation will not constitute a divorce.
Secondly, you have not mentioned the reason why your wife is against your family members. What is exactly the nature of the conflict that causes your wife to do that? Is she just against your family for no reason or is there a reason for it? Without this vital information we cannot advise you properly.
Thirdly, you should seek out the assistance of a local scholar that has experience in dealing with marital issues and get marital counseling. 
 
Lastly, make constant duā (supplication) for yourself and your wife that Allah put love and harmony in your relationship. The following duā from the Quran is very beneficial in this regard:
رَبَّنَا هَبْ لَنَا مِنْ أَزْوَاجِنَا وَذُرِّيَّاتِنَا قُرَّةَ أَعْيُنٍ وَاجْعَلْنَا لِلْمُتَّقِينَ إِمَامًا 
“Our Lord! Grant us from our wives and our offspring who will be the comfort of our eyes, and make us leaders for the pious” [Surah Al-Furqan 74]
 
And Allah Ta’āla Knows Best
