My Bd doesn’t think the baby isn’t his and hasn’t brought him a single thing and now wants a dna test

Well my Bd knows the baby is his but we got into an argument and he spoke his true colors . He doesn’t think the baby is his and wants a dna test . I was messing with a older man but just for money purposes( no judgment please) but I never messed with him raw. Plus my bf knew and didn’t give af , it really hurt my feelings... I stopped messing with the man begging of January, like the first . I had a period on the 15 and it said I conceived on the 29 . I never messed with that man raw only my child’s father . And I told him before I got pregnant I would give him a son and that’s what I have . The baby looks just like him in the pics and now I just feel he has me self conscious and I don’t even know if he wants to be there for the birth. I told the old man about the situation and he said he wishes but he even knows it can’t be possible. At that my childs father hasn’t bought the baby anything but has been playing the daddy role and been acting all excited up until we got into it and he said that. It really hurt my feelings ... I just don’t know how to think anymore , no judgement. Words of advice please ??
