Agree with @dillite, despite what he proclaims, Danaconda is no Ride or Die, Clyde-to-her-Bonnie, Gentleman. DyaknowwhatImean?
But he’s certainly taken Bec for a ride and let her die of shame.
Agree he should’ve given her more warning and let her down gently. Rather than shagging her 4 times a day at the bitter end, when he’d apparently already decided she wasn’t a great option for a stable family life.
Did she deserve it? I think so, because she allowed herself to believe (and even tried to “manifest”) his love for her, despite his constant anxiety-blinking. Apparently totes unaware her sozzled slanging might’ve given him the ick.
