Thoughts on Shaina?

I know I'm a little behind on watching Love Is Blind but I cannot figure out my stance on Shaina girl. From day one she was a little off to me, then I got even more confused when she said yes to Kyle instead of Shayne. We knew she was religious and how important that was to her, so why did she say yes to him??

I just now finished Episode 6 where she not only officially breaks up with Kyle but also confronts Shayne about his relationship. Major red flag when she said "oh, so obviously you're not comfortable enough in your relationship that you have to bring me into it"........ girl what? It left me quite perplexed.

Natalie is a sweetie so I hope nothing more coo coo happens with Shaina. What is everyone else feeling?
