The law of Islam has created several solutions and lines of defense for family before resorting to divorce ...
allah said:
وَاللَّاتِي تَخَافُونَ نُشُوزَهُنَّ فَعِظُوهُنَّ
وَاهْجُرُوهُنَّ فِي الْمَضَاجِعِ وَاضْرِبُوهُنَّ ۖ فَإِنْ أَطَعْنَكُمْ
فَلَا تَبْغُوا عَلَيْهِنَّ سَبِيلًا ۗ إِنَّ اللَّـهَ كَانَ عَلِيًّا
كَبِيرًا
As for women you feel are averse, talk to them suasively;
then leave them alone in bed (without molesting them) and go to bed
with them (when they are willing). If they open out to you, do not
seek an excuse for blaming them. Surely God is sublime and great.
[An-Nisa:34]
and said:
إِنْ خِفْتُمْ شِقَاقَ بَيْنِهِمَا فَابْعَثُوا حَكَمًا مِّنْ أَهْلِهِ
وَحَكَمًا مِّنْ أَهْلِهَا إِن يُرِيدَا إِصْلَاحًا يُوَفِّقِ اللَّـهُ
بَيْنَهُمَا ۗ إِنَّ اللَّـهَ كَانَ عَلِيمًا خَبِيرًا
If you fear a breach between them, appoint one arbiter from the people
of the man and one from the people of the woman. If they wish to have
a settlement then God will reconcile them, for God is all-knowing and
cognisant. [An-Nisa:35]
And when impossibility of married life, the divorce is the last solution to keep this family, but for the divorce terms and conditions and controls, the Muslim should abide by it.
allah said:
الطَّلَاقُ مَرَّتَانِ ۖ فَإِمْسَاكٌ بِمَعْرُوفٍ أَوْ تَسْرِيحٌ
بِإِحْسَانٍ ۗ وَلَا يَحِلُّ لَكُمْ أَن تَأْخُذُوا مِمَّا
آتَيْتُمُوهُنَّ شَيْئًا إِلَّا أَن يَخَافَا أَلَّا يُقِيمَا حُدُودَ
اللَّـهِ ۖ فَإِنْ خِفْتُمْ أَلَّا يُقِيمَا حُدُودَ اللَّـهِ فَلَا
جُنَاحَ عَلَيْهِمَا فِيمَا افْتَدَتْ بِهِ ۗ تِلْكَ حُدُودُ اللَّـهِ
فَلَا تَعْتَدُوهَا ۚ وَمَن يَتَعَدَّ حُدُودَ اللَّـهِ فَأُولَـٰئِكَ
هُمُ الظَّالِمُونَ
Divorce is (revokable) two times (after pronouncement), after which
(there are two ways open for husbands), either (to) keep (the wives)
honourably, or part with them in a decent way. You are not allowed to
take away the least of what you have given your wives, unless both of
you fear that you would not be able to keep within the limits set by
God. If you fear you cannot maintain the bounds fixed by God, there
will be no blame on either if the woman redeems herself. Do not exceed
the limits of God, for those who exceed the bounds set by God are
transgressors. [Al-Baqara:229]
