The truth

By Anonymous - 29/06/2026 20:00 - United Kingdom

Today, I was asked to donate blood for our daughter but it turns out I’m Type O while she is AB, so there is no chance she's my daughter, and my wife cheated on me. So I asked for our other two kids' types. My son is AB so he’s not mine. Our other daughter is O, so she might be the only one that's mine. FML

Unfortunately, an AB child needs an A from one parent and a B from the second parent, regardless of whether the parents are A, B or AB. If the poor guy here is type O then his kids can only be O, A or B. Even if mom is AB the kids could not possibly be AB and have a type O dad. So unfortunately she most definitely cheated with another guy who is either A, B or AB

This must be more rage bait from a dope who won't give necessary info, like the wife's blood type. If she is AB, all the kids could be yours. But by all means, accuse her of infidelity rather than gather facts.

At least you're not O for 3. At least not yet.

A blood test is NOT an accurate paternity test. There have been several well-documented contradictions and exceptions involving blood types and paternity. You have every right to be tripping because it's very rare. I looked deep into it. typically if your an O type blood you can only have a child that is O, A or B type. not AB. but there are documented exceptions. you will need a dna test. I wouldn't jump to conclusions. There’s a reasonable chance she didn’t cheat.
