How do i get rid of sperm donor>?

I was sleeping around with loads of different guys because I just wanted a child. I was mainly sleeping with blacks and asians coz I wanted a mix race child so my baby will have a natural tan. One of them finally got me pregnant and I had his child but I don't even like him. He not even good looking. He looks like a posh geek and I just don't fancy him at all and he is abit ov diked. He never made me feel special at all and we have zero chemistry. I hate the fact that he the father of my child. I wish one of the other guys was. I been with way hotter guys than him. Why did he had to be the dad. I didn't care too much though coz I I didn't want any guy involved anyway. I just wanted me and my baby. He was just a sperm donor as far as i was concerned. I did tell him I was having his baby though coz I needed the money off him so I could buy my baby loads of nice things and he had a good job. Thats the only reason why I told him I was having his child but it was the biggest mistake I ever did telling him. I should of just fcuked him off as soon as I found out and then none of this would of happened. I could of managed without him. I didn't even get much money outta him anyway. He even had the cheek to ask me to get an abortion and he was never there for me during my pregnancy and yet he wanted to be at the birth. I told him to fcuk off. After I had my child he was bombarding me with calls and texts asking if he could see her. I told him I wanted nothing to do with him and to leave me alone but he wouldn't listen and he managed to get in touch with my family and got all my details then he contacted a solicitor and he demanded a dna test. When the test came back positive he went for custody for my child and he won and now she lives with him and I hate him for it. I want to kill him. I don't want him involved at all and I don't want anyone to know he my babys daddy. It embarrassing to my rep if people found out. He now wants to change my babys name and add his name on the birth certificate. He won't even let me see her and he is rubbing it in my face that he has her and I really hate him for it. I want him out the picture and get my baby back. He didn't even want her originally in the first place. He only wanted her as soon as he saw her coz she was so beautiful. I hate him. How can I get rid of him and get my baby back. She belongs with me. She would have a better upbringing with me. I have a large family he doesn't even have much family in england. He is also a muslim and comes from a religious fanatic family. I don't want my child growing up wearing a hijab. Seriously how can I get her back. Any advice on how to get him out the picture and to get my baby back. She belongs with me.
