1) The wife must always be creative in her intimate approach towards her partner and vice versa. Grooming oneself and always trying to have an appeal towards each other is very important to increase love between husband and wife.
Respect for one another and use of intimate loving words are also importance.
2) As for avoiding divorce there has to be mutual respect and to give regard to each other’s privacy. Avoiding arguments, disrespect and coarse language can help a lot in keeping couples from growing apart.
