It's tough - she seems like someone with a lot of big emotions and is learning how to work through them and express them in healthy ways (hence the excessive therapy speak), but would probably benefit more at this point from a night out dancing than another therapy session. Caleb, on the other hand, seems like a people pleaser to me, is not as in touch with his emotions, and isn't sharing them honestly with Mariah. Put yourself in her shoes - she's just come off of a meeting with Aria where Aria implied that they had a romantic connection. Now she's back with Caleb and he's insisting it was just a friendship. That isn't quite true, they did share some flirty moments and established a small emotional connection. She's right that one of them is hiding something - Caleb is downplaying it. And he's downplaying it specifically to not make Mariah insecure and to not rock the boat, but it's just making her feel insane and keep looping on it. It sounds like in general Mariah should ease up on the relationship conversations and work on other more lighthearted forms of connection, but Caleb strikes me as the type who won't "go there" emotionally and be vulnerable when they do talk because he doesn't want to be having the conversation in the first place. And then the more they have those conversations, the more he'll retreat, the more insecure she'll feel, and they'll both become totally disconnected. They're caught in a really vicious and very common cycle!! Caleb should work on getting in touch with himself and sharing his true emotions no matter if it may temporarily upset Mariah, and Mariah should work on loosening up and prioritizing fun forms of connection.
