Well, as hard as it sounds, you'll probably be better off w/o her. I'd look into the legal side of things if you wish to be the child's legal protector. As they've said above, research your options and contact a lawyer after that if you still wish to pursue the matter. I say the first part b/c this is the same gal who was ready to drop you in a flash over an alleged incident. Seems she either has been cheating on you longer than you suspected and was looking for the first excuse to cover her own infidelity or she's a verrrry jealous person. Even if things seemed ok while she was on her older prescription, she was still unfaithful by your account and apparently doesn't have the same feeling you share for her.
