I'm glad that definition is sperm donor, bc my husband's baby mama said that about my husband but yet he always tried and wanted to see his baby, paid his child support Religiously, in fact it came out his check for 6 yrs. She was mental and was so obsessed with him b4 I met him amd after, she stalked us, tried everything to ruin our lives, would go MIA on him for months and few yrs hiding his baby bc she said if he wasn't gonna be with her he couldnt see his baby. He seriously is a WONDERFUL dad and man. She even admitted to him in front of me on text b4 him and I she was so obsessed with him she been wanting to have a baby with him to get him to want to date her and be a family so she watched her ovulation for over a yr and wanted booty calls around that time and made sure she got pregnant. Then was made he was qith me and has been with me since the baby was born 8yrs ago. Anyways she lost custody and now my husband has full custody bc she kept the child from him on purpose for 2 yrs hiding from the judge and had the child in hotels homeless shelters abandoned homes so on and so forth.

Sorry that u are going through that but yes take all that evidence and take him to court for sure
