tell him you'll prove it with a DNA test.

I was nice and put FYL, but for future reference, it's a lot easier for the father to just up and leave you if you're not married to him. Think about that next time. And apparently you ex doesn't know jack about genetics. It's possible for two dark haired parents to have a blonde baby.

Tell Him Tell Him Tell Him! =(

wow... yeah thats horrible I'm the same... I had blonde hair as A child but now have brown hair...

I'm a caucasian with brunette hair, my husband is black, and our baby had blonde hair. It can happen to anyone! I was also a blondie when I was born. You will get through this, get testing to prove he's the father if there's any doubt with child support. Don't let the idiot get away with this!

A simple blood test could fix this problem. I don't see why he wouldn't just ask for that, unless he simply looking for a way out of the relationship...

Start a paternity suit. Get genetic testing; ensure he supports the child!

I think your BF needs a lesson in highschool Biology. Blond is the recessive gene, so a brown haired person could be carrying one brown hair gene and one blond hair gene. If both you and your BF have a blond gene and a brown gene, and your daughter got a blond gene off each of you, she'll have two blond genes and that'll make her blond. It's more sus when you have two blond parents and a brown-haired baby... (although that is actually possible, just very rare.) Both my parents have brown hair (my dad's is so dark it's almost black) and me and one of my sisters both had very blond hair when we were little.

Come on, how can we actually be expected to believe a guy would break up with a woman over this? I could understand maybe if the child say, came out looking of Asian descent and both partners were black, but this is silly. He probably just wanted out of the relationship and lied about the hair thing. Sorry, OP.

In response to the whole "You should have been married" team - I neither agree nor disagree. All I can say is from personal experience, being married doesn't stop a man from walking out the door. My mother and father were married years before I was born, and he still left when I was small. My aunt was married when she had my cousin - my uncle left her, we have a friend of the family who was married, and the wife decided she didn't want to be. She left. They had a two year old, born after marriage. Being married just makes it that much harder; child custody, and divorce hearings etc. . . If a guy is going to leave, a wedding ring on his finger isn't going to change his mind. So in all honesty, her being married has nothing to do with what her boyfriend did. I do, however, agree on the paternity test. If he's that insecure, I would get one. No simply to get him back - if he's going to dump you for that, he doesn't deserve you - but as proof that he IS the father, and he IS responsible for child support.
