She slept with two men.

None of the three were "GUILTY!!!!", but only one was the real father.

Nobody's blaming anyone more than anyone else for the conception. That is another argument for another day that you have brought up.

This is about who takes responsibility.

The real father escaped responsibility.

The non-father took responsibility. At that time he did a good thing by doing so.

Years later, the non-father decided he wanted to change his mind.

The context at this point was different though as it wasn't just about him any more, and that's why he's wrong to want to.

The mother knew the child ould have been fathered by either of them, but kept schtum.

Just as the non-father eventually figured it out, so the child probably will too.

It will be a source of a great deal of emotional turmoil.

The mother has that on her conscience.

None of it is the childs fault, and the child must not be punished or suffer any form of upheaval that might lead to problems later in life.

The non-father must therefore honour his commitment.
