Left my abusive husband

Last Sunday I kicked out my abusive husband of 6 years after putting up with the abuse that started just before I was pregnant with my son. Suffered abuse while pregnant and throughout the first year of my son’s life. I left for a week at the 6 month mark in September 2022 and he and his mother begged me to come back. I tried to kill myself while on holiday when he abused me again in February 2023 and he stopped me. Somehow we managed to put this behind us and thought that would be the end of it. I now have a 3 month old baby girl and he’s done it again after 2 years. I have now shared with my family and friends who I have been protecting from the truth of our relationship this whole time. After having a daughter I have to do better to stop this abuse and get away. I’m still mourning the life we had and the daily hum drum that comes with little ones and no idea how to make sure our son doesn’t feel any of this before his 3rd birthday next week. Has anyone had any experience to support in this time? It is breaking my heart over and over again while my little boy is crying for his dada each night and wondering why he can’t go to grandmas house which he is used to doing almost everyday! Still feel like I’m the one breaking up the family even though I know I haven’t done anything wrong.
