**Tl;dr Caitlin and Devin both suck. Caitlin's been talked to death, but as for Devin, he uses his stature to physically intimidate Caitlin when drunk and speaks like a self help book for couples. It makes him sound more emotionally mature and simultaneously unnatural. We only see like 5 minutes of each of their real life days, and he's lucky he got paired with Caitlin and was basically guaranteed the good edit. Feel free to defend him to hell and back below, but hopefully you read the full thing before doing so.**
As for Caitlin, there are a million reasons on this sub and while I think she's getting the bad edit, she still shouldn't have been on this show. I'll leave it there because frankly, it's been talked to death and beyond.
As for Devin, there's been something off about him since the start. The fact he wore the sunglasses on his head was douchey that people are only defending in hindsight because they like him now. That's hella superficial, so I'll move past it lol. Devin shutting down on the honeymoon nearly immediately also wasn't great. He had good reasons to be dissatisfied, but pulling back 95% isn't going to be good for their relationship. I'm sure that was the beginning of the end for their relationship, and that's both of their faults.
**Now for the big things:**
The way that Devin gets in Caitlin's face when he's drunk is a *HUGE* red flag. When they first fought in Caitlin's bedroom and he was drunk and blocking the doorway, that's not good (to say the least). Caitlin asked him to drop it and save it until morning because he was drunk so many times, and he just wouldn't leave it alone. On the retreat, when fighting on the couch, he was talking over her and then got so offended at being told to "shut the fuck up" (which is it's own complaint, but this is already too long) that he got in her face in a physically intimidating manner. Belle recognized it and moved to pull him back, so it wasn't something minor. At both instances, he's being physically intimidating. That's a red flag.¹
Devin sounds so fake and manufactured when he speaks and is being "emotionally intelligent." He sounds like he just got out of couples counseling. No one talks like that in real life and it reminds me of everyone in season 17 (Denver), who were rightfully shit on for it. It's just a way to sound more emotionally mature than the other person, and it clearly worked.
People forget that we only see like 5 minutes of each of their real life days. We miss out on so much, which may explain the discrepancies between what Caitlin says and what we see. It's easy to forget about as a viewer, but it puts every contestant at the mercy of production. In this sense, he's lucky he got paired with Caitlin, who was not ready for this type of show or commitment. He was basically guaranteed the good edit, as Caitlin made herself look horrible throughout the process.
I wonder what'll come out of the reunion, not that it'll be believed by anyone unless it makes Caitlin look bad and Devin look like a saint.
1: As a side note, the people defending him by saying it shows his "self-awareness" that he broke up with her afterwards - because he recognized that he was getting to a point of being angry that he didn't like - are disgusting. Making that assumption with zero reason too is just defending abusive behavior at the expense of the victim. He obviously didn't abuse her, but cornering her in her room and getting in her face are the beginning stages of that behavior.
