I have, more than once. When i was 22 i began dating a woman with 3 kids. My latest relationship i was planning on marrying the woman, and she had a son. In fact her son had some special needs. But i loved her, and i was getting to know him still, but i did like him and enjoy spending time with him.
And despite the insult hurled by the above posted, i am not stupid for doing so. My father married my mother, she had three kids. To make it worse she was damaged from her previous marriage, as well as her three children. That didn't make my father love her any less. They married, i'm the only child between the two of them. My mother died nearly 20 years ago, Her kids view my father as theirs as well. One moved out of state, in part to be closer to my dad and the other is living with us. They call him dad. He is their father. He loves them and treats them as if he were their biological father.
So the self loathing poster above may want to think twice before hurling insults at men with enough character and love to marry a woman who has kids.
