Louloute, Sorry to hear you are feeling so sad about things. Emgee is right, human relationships can be very complicated at times. Maybe because we make them so, putting on all the stresses about conforming to rules that the society we live in puts upon us.
There are only two people in your relationship, yourself and your husband..well three if you count God..

You answer to each other and to him. Religion in general has always been used by some as a tool to control the lives of people. It's often misinterpreted and God's true message often lost. You are not here on this earth to be unhappy, you do have a right to a happy life which you have found with your husband. That is a most precious gift, don't ever throw it away because some cause you to doubt. Don't look to hard for answers or try to seek approval for your love. God brought you together through fate, take that as a sign.
If you have children in the future as long as you love them that's all they need. We are only ever custodians of our children until they grow and are able to make choices for themselves, we just support them in what they do with the unconditional love a parent has for a child.
None of this probably helps you much, as you have to find your own answers. I hope you find inner peace soon. Sometimes the answers we seek we already hold in our heart but choose not to see them. Take care.
Oh, one more thing...you are never alone when there is someone who loves you.
