My ex and I never lived together, we both have previous children. His son is 8 and my daughter is 6. We had a daughter together who is now 15 months old. He hasn't saw her in about 5 months. I left the relationship because his son has some issues. My ex was told his son had a sensory disorder a couple years back, he never took him in to get any help and I've watched this child turn from sweet and innocent to cold and unresponsive. He started bullying my daughter, it was getting worse so I confronted my ex about it. He blamed my daughter at first then finally came around. His son would hurt her and feel no remorse, he plotted to hurt her and then when she'd be bleeding he would be so blank and not care that she was hurt. It scared me. so i told my counselor about it and it came out the next day, from my daughter who was 5 at the time that my ex's son had tried to touch her sexually. He pulled his pants down and humped her and so on and so forth. There were other things she said as well, we'll just say it was disturbing. My ex and I were not together but I was bringing our daughter over for visits after my daughter was done counseling. He said he was going to have his son get help and looked at. We decided to work it out as a family. The problem was was that it came out that he was not getting him help, he lied and really believe that he didn't need any help because even after his son was spoken to by his dad and I, he tried it again with my daughter a couple more times. I had enough and I moved back to my hometown, 40 mins away from where I was living. He is mentally and emotionally abusive to me and I went through counseling to get through that. He had been physical a couple times when he was drinking, not every day. He sends me nasty messages and threats now and he was pounding on my mothers door for hours trying to serve court papers to her because he does not know my address. I tried to make this work but now I refuse to speak to him because he is denying anything happened between the children. it scares me and I do not want my daughter over there. Childrens services were involved because I called them but because I keep the girls away from there they can't do anything.
My question is, what should I do? I am avoiding him and being served the custody papers because he scares me. My mother refuses to be served for me because she hates him and doesn't want to be involved. does she have to accept the papers? or will she get in trouble? I'm not sure what I should do but he said he was going to be at my moms door everyday knocking on it. I don't know what my rights are legally and what I have and not have to do in this situation. Any insight would be great.
