If you love the children and cannot care for them adequately, I would move away, stop seeing this woman, start another, more honest life. Exposing the children and disrupting the woman's marriage anymore than you already have would be truly selfish. I am not thrilled with what this mother has done, either with her marriage or her children but she is not here to ask my opinion. You two need to quit messing with the husband and the children's lives, especially as he is supporting the children.
