The research, commissioned by Nickelodeon, found a whopping 46 percent of women ended a relationship because they felt they had to mother their partner a bit too much.
Researchers asked women to reveal the signs which indicate a man is still immature. Some of their top answers included, the fact their guy finds passing gas funny or when he tries to race other cars on the road. It's a definite sign if he still has cartoon sheets and avoids eating his vegetables.
According to the study, another sure sign he's not grown up is if he gets competitive with children at games and sports. The immaturity did have an upside though. One in three people think it helps in bonding with children.
