Isabella as a middle name?😫

So we're having our first girl after 2 boys and I fell in love with the name Adelina, my SO isn't a HUGE fan and he gave me the name Isabella. I feel like I hear it everywhere, I dont like it AT ALL and we're having a hard time agreeing on a name. He said he's fine with me picking the first name as long as Isabella can be her middle name and I'm having a hard time trying to find anything that sounds good. At the same time I dont want to completely get rid of Isabella because we're done after this and it IS our first girl and he seems really happy and set on Isabella but I know I would never be happy with it. It sounds ridiculous but I'm getting my tubes tied after this baby and It's really special to me because we've wanted a girl for so long. Any suggestions?♡

EDIT- My boys are Arthur and Mateo♡
