Is my boyfriend being unreasonable?!?!

My boyfriend and I have been having a ruff time coming up with a name for our second son. We have a 5 year old daughter named Lillian Rane, an 18 month old son named Braxton Thomas and I'm currently 20w5d with our second son.

I really love the name Rylan Christopher ( fathers name is Christopher) my boyfriend has had issues with my dad in the past ( long story) and doesn't want to use his name as our sons middle name. We used his fathers name as our first sons middle name ( Thomas) and I don't think it's fair that my son will have no ties to my family name wise... do you think it's fair to cancel out my fathers name just because my boyfriend has issues with him in the past? ( like 3 years ago past, I thought he had moved passed the issues)
