The reason he picked you was because you were young, had, probably a lack of self esteem, were kind and put others first and he probably thought you wouldn't defend yourself and would be easy to manipulate. Don't be the weak little mouse he thinks you are, find your inner lioness.
Fuck this pathetic little man, fuck his manipulative tears, fuck his enabling mother, fuck his view of you as his punchbag. You are so much more. You are strong, you know that because despite what he's done, he's not broken you. You are a mother, you need to protect your daughter from this toxic waste of skin, and you need to protect yourself from him.

Please look after yourself, call the police if he comes round, do not talk to him. Change your phone number if you can? Some networks will change your phone number for you if you tell them you're being stalked or harassed. Therapy in the long term may help you find some inner strength and belieif in yourself too.
MN is a fantastic resource too, so use it. Any moments of weakness or self doubt, just come back here and you will find support and strength.
