long story short ex was emotionally manipulative tried to get me to have abortion i didn't. he said they wanted nothing to do with me or the baby and abandoned ds before birth. hasn't seen ds or paid a penny towards him and he is 14 months. i started a claim with the cms and have received constant messages, sob story, threats from ex saying he cannot afford it and it will ruin him. he has threated me via a friend saying he will take my son for 50/50 custody and that him and his new gf will raise him half the time, i don't even think the gf or his family even know my son exists. basically wants to reduce payments he has no interest in being a loving parent. i have asked him not to contact me and said the cms will work the payment out yet he is still harrassing me saying can we talk at the weekend. if i block him he will harass a mutual friend. i have a appointment with police as been advised to keep a note of the abuse. i just dont know what to do, he has offered me under half the amount cms would give me. do i take this for a easy life i know he is trying to manipulate me but the thought of my son being subjected to his narcism fills me with fear
