I see both points, Stephen and Jamelia and Chris. Chris was not in the wrong to want to go on a date with Lou. He wasn't exclusive with Jada and both seemed interesting.
However, the situation had been created of making him choose in front of Jada after having sex with and spending time with her.
It put him in a rough position after several dates he had no interest in and he treated it like love island (even the language he used) not a mature, diplomatic man.
Stephen and Jamelia I think were saying accept you've been put in an awkward position for TV and behave with more humility to the one you've slept with and built intimacy with rather than suiting yourself.
Jada well within her rights to feel hurt. In real life that would never happen. I think she just removed herself from a humiliating public position. Chris probably did the right thing, it was just unpleasant that Jada had to see.
The brunches are ugly. I think it's the 'civilians' who bear the brunt of the rejection and humiliation. Fine picking a match after a mixer but not several dates and sex. That's really messy and nothing like real life or ethically helping people find partners.
Tristan thought the girls were only FWB material anyway hence going scorched earth.
Who the hell does Stephen think he is, the redheaded guy was really attractive. No need to be personal.
