I am wondering if the husband is allowed to impose the likes and dislikes of his parents on his wife and claiming that it makes him happy if she follows it. If the wife decides not to adhere to that decision knowing that he is asking her to please his parents, is it okay for her to refuse the request/decision? or religiously she has to do adhere to it?

Such imposing is not correct however there has to be an understanding between the couple and compromise so that the relationship flourishes and strengthens. Each has needs and so both need to sacrifice and compromise for the other, on issues that are not core or fundamental such as faith.
