Which middle name?(read description)

I love the middle name Rose..it flows nicely and is pretty..but my entire pregnancy(37weeks) I've tried finding names that no one in my family has..but one person does have the name Rose..plus the biological father(he lives across the country and wont be around much) has another daughter with the initials A.R. as well..not a fan of repetitive names or initials..

But I also like the name Kari..I know it doesn't flow as nicely as Rose..but my boyfriend..who I was with for 3 1/2 years, and we were engaged got back together and has decided to step up and be the father figure in my daughter's life..so I want him to feel like how he feels and what he wants is shown..it takes a lot for a man to step up for someone else's kid. He wants to help raise her like his own..so I really took into consideration the middle name he choose.

I can't decide!
