Am I wrong?

Sorry this nay not be in the right group if it's not I'll move it. Anyway my dad was diagnosed with cancer last year and I'm named after my dad well he messaged me today because my cousin wants to name her baby after him now aside from the fact that I feel like it makes me being named after him less special and idk irrational as it is it makes me feel like I'm being replaced this cousin molested me for years when I was a kid before I got up the guts to tell my mom about it and now she wants to name her child after my dad and me since it's my name too and he wanted to know if I was ok with it I told him my feelings on it and he said he would tell her to pick another name but I'm kind of upset that he didn't just tell her that in the first place especially considering what she did to me when I was young that he is well aware of but with him being sick and I may never get to have him walk me down the aisle or meet my kids because I'm still ttc with no success for 2 years I feel like my name is all I have from him that's all mine no one else can have it all my siblings have kids so they get to have memories of Grandpa and he gets to know them and that's something I may never have so I want his name to just be mine I feel stupid writing this but I really did start crying talking to him about it.
