Sometimes men say things they don't mean. You have no way of knowing what he is going to say until you tell him. You are not a mind reader, so until you tell him, try not to assume what he is going to say. If you tell him and he says he is leaving, then he apparently doesn't love you as much as you thought. You are not a child. You are a grown woman and should have been protected with birth control. At 22, and not married, with one child, I am surprised you didn't take precautions. You have some tough choices to make. But do not make them lightly. This is a little life now, who didn't ask to be in the middle of this conflict. You both have to sit down, and decide what is best for all of you. Don't plan to leave yourself until you talk to him and make sure he wasn't just saying those hurtful things out of anger or frustration. If he leaves, you will have to make the choice yourself. It's not going to be easy, but I hope that this will make you be more careful in the future. Good luck.
