Men change after marriage for a number of different reasons.The main reason is bcz they r not satisfied with what they have.No matter how beautiful,forgiving,supporting or loving a man's wife is,he'll always feel as though he has missed d better bus.
Another reason for d changes in man after marriage is d marital contract.Once he obtains a woman's signature & her "I do", that is all he needs to feel secure that she can't get away & must deal with his many flaws & shortcomings.He may no longer feel d need to impress her,woo her,or even tell her he loves her once she's locked down for life.
Some men r emotional carpenters.They enjoy building d shelves of marriage,only to sit their wives on them while they go & work, hang out with their friends,or chase d better bus.These types like to know that they have a lady at home,but they don't put much effort into giving her a reason to stay there.
Men also enjoy the thrill of d chase.Once they obtain a woman's hand in marriage d chase pretty much ends.Sometimes d thrill ends as well.
Not all man change in these ways after marriage.There still r a handful of chivalrious,loyal,attentive men out there.
It is also not only men who change after marriage.Women change as well.
supported you did your home work very well
