I would have to agree with your C. Because my girls' "sperm donor" or whatever..I refuse to call him father or dad. We went to court, and I told my lawyer I didn't want child support at all. From him, because then he could get atleast supervised visitation and if he did well he could get unsupervisted to taking me back to court and try and get part time custosy. I basically told her, that if he isn't going to be around, I don't want him around at all. He would screw them up mentally, emotionally, pscyhologically. On every level. I wanted to just cut ties with him and do it on my own. Where I knew his influence would not harm the girls. His presence alone, could have caused pain for them. I know he is not responsible, he is not consistant, he has no cares but his own. I didn't want that for my girls. My bf is the best father, and he is truly their dad. They call him Dad, they do stuff with him, he protects them, provides, loves them and nutures them as his own. I am glad it worked out that way, they would have been so confused. And my middlest's knows (J. sperm donor) as a bad daddy. Not because of what I have said, because all I have ever told her is that he was sick, and he needs help. Which is true. But not mean. He has major addictions, drugs, pornos, drinking, and he is extremely unstable. I was never brought up that way, I was brought up in a strict Christian home. I wanted my kids to have a stable life. You should fight for sole custosy, and get him to be denied all access from your son.
