Is it a red flag?

Is it a red flag when a guy is constantly texting you and jokingly calls you his wife. I've been going along with it because I mostly thought he was joking, but it kinda freaks me out when he says shit like he wouldn't be okay without me and how other guys wouldn't think I'm a 10 because I'm clumsy and dorky and a huge goofball, but he does. Like I don't think I'm a 10 at all, but it makes me uneasy that he says stuff like that. For context we've been texting for a month and we've only gone on a few dates.

Thank you everyone for the wonderful advice. I ended up discussing it with my friends and I decided to end things because bro started being too crazy for me.
