I'll make this short. I see a lot of men on here that claim, "it's the womans fault she's a single mother, she drove him away". Anybody that says that is selfish and morally unsound. I don't say that as an opinion, I say that as an indisputable fact!
Lets pretend that she was a bad girlfriend/wife and that's what 'drove him away'. I'm more than willing to concede that that happens. He has every right to end a toxic relationship. However, their is a considerable difference between ending your relationship with a woman and exiting her life entirely.
When you end your relationship, you're walking away from her. But when you exit her life... at this point you're not walking away from her, you're walking away from the child/baby! You don't have to live or have a relationship with a woman to be a part of a child's life. Believe it or not, it is possible for a man and a woman to co-exist even when not in a relationship.
Clarification: When I say single Mother I mean that the Father is not part of the childs life.
