Welcome to HealingWell. And to the depression forum. I don't know if what you are describing as depression, but it sure seems that you feel that you have gotten yourself in a pickle.
First of all, if he loves that soon to be baby and his girlfriend, not much you can say or do will split them up. Though we don't know what you actually said. If he is a good person and unselfish, he will do whatever is right for the baby and the situation. So stop feeling guilty about it.
Secondly, we all make mistakes, this is a part of learning and growing up. Just don't get into anybody elses business and tell lies anymore. It isn't the end of the world, though I imagine that you feel like it is. So learn from what you have done and move on. Be a friend to both of them, not just him. Think of the child as you are and don't repeat what you did. Don't try to get them back together either, stay out of it. You will be much happier that way.
I hope that this helped some.
