Moving On

How do I move on from my baby father ladies. I rather not go into major details about why, just know I'm being neglected, cheated on and emotionally abused severely. I've been emotionally abused since before we got pregnant but since I'm having a little girl and she has to look up to me , I REFUSE to let her see me get drugged by her father. I'm done. How do I get over the crying stage. How do I legit become emotionally unattached from him?
