I don't think she'll ever have a name

Why does it seem like EVERYONE I talk to (who is expecting, obviously) already knows exactly what they are going to name their child?? Jon and I canNOT agree on anything. Everytime we think we have come to some sort of conclusion, one of us decides within a couple of days that we hate it. We want something unique but not weird, you know so she doesn't go to school with 5 other girls with the same name? So far these names have come and gone

Halle

(don't hate it, don't LOVE it)
Rylie

(decided it sounded too much like the made up name my sister gave her kid, "Retlee")
Cadence

(But what would we call her for short?? Cady... come on! That's MY name)
Chloe

(again, don't love it)
Reese

(this one is my fav, but Jon's not so hot on it)
AND if Jon had his way Sevin

(like from Seinfeld, and no people, this is not a joke. I get mixed reviews, some love it some hate it. We would call her Sevi. The more I hear it the less I hate it, but I just don't want her to get made fun of)

And don't even get me started on the middle name. I want it to mean something and Jon couldn't care less. My middle name is after my grandma and I want to stay with family tradition. I don't know why, but I get anxiety way bad about this. I just wish we had her name settled on. PLEASE PLEASE PLEASE has anyone else had this hard of a time with this? And please if anyone has suggestions let me know, we are almost desperate at this time.
