First of all you must understand that your partner is an adult, the established people. Each of you brought up in different families with different structures. Therefore, the basis for a strong and happy marriage is compromise. This is a skill that not everyone is available. Most of the people difficult to accept and come to terms with the habits of the partner.
Do not worry because of the little things, if you do something really important to discuss this with her husband. Let me leave it at least a part of his habits, even if they will be able to prevent. If your partner has had a fascination before marriage, then let it remain and after. You clearly need to be aware that he may be his occupation, which he is interested. Maybe in time you will even share his hobby.
Remember, you are not one body with her husband and two completely different people. A prerequisite for marriage should be a pleasant comfort. Psychological and emotional comfort. Coming home, you and your husband should feel a sense of relief and peace. My house - my fortress. Try to be for each other a good friend and a strong arm.
Sex life is an important part of marriage. Pleasant joint life includes joy of sex. Do not deny her husband for no apparent reason, learn to relax in bed. Small savory surprises will make a variety in your relationship with your husband. Surprises can be not only an intimate nature. A delicious dinner by candlelight can be a great gift that you can organize without special reason.
Learn to feel the mood of a loved one. If your husband came angry and irritated, the usual silence on your part can be accepted. Of course, understanding of each other comes with age. However, try to take into account another's experiences and mistakes of others. Be smart and do not make the life of a loved one in a daily nightmare.
