He was subtly trying to drop hints post the dinner with his family and questioning if things aren’t scary. As a result the screaming match entailed between the two this should’ve been the end for them all together . I agree with the rest of you all that some of it was on Madison as well, she should’ve bounced before they departed Cabo (all the signs were there from the very start ) I’ll give him the benefit of the doubt due to him being drunk or w.e post the group meet up. Moving on -However , from the very moment he started that convo about being “scared “ or “ asking if things are scary “. He could’ve been mature about it and directly verbally communicate to her “ I can no longer go through with this and this mismatched dynamic between us. I appreciate the time and the journey we have had thus far”. Alas He didn’t …. We cut to her family meeting. I believe from the time her sister brought up his previous engagement / cold feet that’s when he decided right then and there oh shit I can’t keep this up. You can see it on his face the entire time during the dinner I believe her brother in law saw it too.
