Stumped on boys name.

So, my boyfriend and I have agreed fully on our girls name: Kaislee Aurora Jean. But for the boys name he wants to name him Dustin Matthew Lee.. I'm okay with the Dustin and Lee, but Matthew is my dads name. Ever since getting pregnant my dad has started coming into my life again, I know I shouldn't hold a long grudge against him. But when I was 13, he chose a female over me and I hadn't talked to him except a few times over the years. I'm now 19 and I have no intentions of naming my son after him!  I keep getting told I should do it because that's my dad, but he caused a lot of pain in my teenage years he left when I needed him the most! Am I just being a b*tch for this? Or does anyone else get my point...
