I knew about no kids from the beginning, and a few months ago he mentioned how he never wants to get married because it scares him, and he was almost married before to his childrens mother and that they ended 6 years together with her cheating and leaving him so that's a huge part of why. I am very happy with him, so I guess a part of me has in the back of my mind that if we maintain a good relationship like this for a while that he'd change his mind.
