my boyfriend doesn't want our son named after him? :(

Liana
I will find out what I'm having in two weeks but I have a gut feeling it's a boy. I have girl names picked out but my boyfriend is the 3rd in his family and I really wanted our baby boy to be the 4th, seeing as his dad died and I wanted something special for him. Should I just let it go and choose another name or try to talk to him?
