Your girlfriend is projecting her fears of abandonment onto you — when they really have more to do with other people in her life, and are not problems that YOU can help her with or solve for her. Her upset at not getting enough attention has more to do with the fact that she’s not living with or dating the father of her new baby. But since he’s not around for her to get upset at, you’re the target.
Your wanting her to be happy is noble, but shortsighted. She has problems that she needs to sort out and as long as you’re around, you’re going to help her cloud the issue so she can avoid the real deal. She may bounce around from guy to guy looking for attention and a sense of security to heal old wounds, but that’s not your fault or your problem or your issue to fix (you can’t).
Unfortunately, the best thing you can do for all three of you (she, yourself and the baby) is to move on. You’ll eventually be relieved, but it will be hard in the short run. Look to the horizon. Keep your eye on the ball. Move on.
