Search Results: questions to ask on an interview

I read an article in some men's magazine it was titled I think
"The ultimate betrayal"
some poor guy moved out if state for work an his girl friend moved with him a few month later. She was happily pregnant with his kid. He married her after the child's birth and a year later she told him the child wasn't his that she lied an cheated on him on her going away party.
his mother had just died of cancer and a new child made him happy until he found out it wasn't his. He recounted taking pictures down and his family feeling sad over losing their first grand child "it was as if my son had died."

Then some medical/research data showed that 55% of woman are willing to lie to their current partner about being the father of a child if it wasn't his, just so he wouldn't leave them. I don't have the reference unfortunately so you'll just have to take my word for it.

it was one of those cautionary tales that probably happens 1 per 100 couples but would it be unethical or trust issue if a man was to get a paternity test just incase. It happens to some guys... so it could happen to anyone one of us really.

Could it also be done without the mothers knowledge or would it be a question that would ruin the relationship? It's a touchy subject so I thought to be a good question to ask.
