You are ENTITLED to be as mad, angry, and hurt at him as you want! Fortunately for you, your child is young and will not remember anything about what went in terms of mommy and daddy's split when she gets older - and even though she is a daddy's girl, keep in mind that you must do what is in the best interest for both of you. Neither of you deserves to live in a relationship that is built on lies: it is as unhealthy for you both. Take whatever necessary steps you need to in terms of taking him to court to get child support, alimony, etc but just do not allow your child to know that you have "bad" feelings in terms of daddy - never say anything bad about him around her as much as you'd like to. Realize that she will love her daddy no matter what happens between the two of you - you need not be civil to him in private, but only when dealing with your daughter. And make sure he is to do the same.
She is also at an age where she has some comprehension of what is going on - she will realize that daddy is not living with her anymore, and it will effect her emotionally. But you CAN talk to her and reassure her that, even though he does not live with you, she can still see him whever she wants. Have her draw pictures for him, and allow her to call him on the phone when she wants to, and remind her that her daddy loves her. She will be okay, I promise. Do not ever feel guilty about leaving him, you are doing it for the long term sake of your child. Just try to stay as composed as possible with him when the baby is around.
good luck, Im pulling for you!
