Before I decided to revert I had great respect for my husbands religion and threw myself into learning as much as I could about Islam, and had begun to teach my children Islam, becuase I promised my husband we would raise our children as muslims. It is important to think about the future when deciding to get married and the children that could come from your marriage, I can tell you from experience my husband was married before me, and he was married to a catholic woman they are now divorced and we are having a very hard time with his 14 year old daughter, and getting her to be muslim, she wants to be like her mother. Insha allah all will work out for you.
