How do i tell my pregnant gf i want to break up with her?

Take into account that her hormones are going insane and it's going to cause frequent mood swings and irritability. At the same time she's probably frightened by this and is taking it out on you, instead of running away and leaving her to cope with something that is your responsibility as well as hers, man up and deal. If you decide to run that's your choice but think of what you'll do to that child when he/she wants to know why daddy isn't around. Your gf will have to tell you child daddy didn't love you enough to try working things out or sit down and talk about things.
