Mama advice or just moral support..

Any advice from the moms out there who've dealt with a narcissistic vindictive baby daddy that had gone as low as to calling CPS and making accusations against you, using your past addiction/recovery and PPD as ammo to the point of your not even tw month old baby to be taken from you and put in temporary placement..2 weeks before mother's Day just out of spite to hurt you because you no longer wanted to give in to his demands and beg for help and rather go through the court for paternity and child support since he has not done anything or help get anything for his baby since he was born. He hasn't bothered making time to even come over, just excuses on wh he doesn't have time. living only 20min away, Even though I begged hin to please help a bit and spend time with his son. My baby boy hadn't even been out of the NICU for a full month before my baby daddy started all this. Im just at a loss emotionally and mentally.. especially so close to mother's Day.
