You've been sold a load of hogwash. You're working, 24 hours a day and 7 days a week with children in the house. Even when you are asleep at night, you are there ready to protect your children in case of fire or other emergency. You have every right to be tired, and you could have sex swinging from a chandelier and still be tired because of the nature of your daily life. If you and your husband want your life together to change, together you must change. That means both of you. The total burden shouldn't be placed on you and no amount of trashy lingerie or catering to your husband's sexual fetishes is going to fix the real problems in your marriage. The next time your husband leaves you for six weeks, take that time to sit down and decide what you want your life to be like. When he comes home, ask him to do the same. Then together the two of you should sit down, fully clothed, and compare your wish lists. If you need to, get a marriage counselor to help.
