I am in my late twenties, never been married and don't have any children. I am dating a guy with two young children. Things have gone really well in our relationship and have even disscused marriage. I love this man and can't imagine life without him, but we have an issue. He doesn't want any more children. I on the other hand would really like children of my own. I don't know if being a stepmom will be enough for me. Do we have a chance, or is this relationship doomed?
