Honestly, it almost kinda of scares me that she may be turning around.
I hear this one loud and clear NDDT. Just continue to do for you man, do not call her, email her or contact her in anyway...unless absolutely need to about your kid and even then...keep it brief. MOVE ON. You are in a tug of war match and you need to drop the rope buddy. That doesn't mean be a jerk. You continue to be the nice caring guy...but let her come to you to see it.
