Adrian, the honesty box and being a dad
I thought his answer was perfectly fine and honest. He never said he would outright not love Awhina's kid as much as one that was biologically his, just that he doesn't know - he's never been in that situation.
I understand that can be a worry for her but there's so much uncertainty in this show, you need to give it time. If living location was a deal-breaker for someone, would they balk if you said "yea, on day 2 of knowing you I am not yet positive I would move for you" - surely that's normal, why is this any different?
Acknowledging it can be upsetting to for her but to turn confrontational and making passive aggressive comments to him for being honest and not unfair seems, well unsurprising for this show but still a shame all the same - especially as it seems there's now a pile-on on him on this sub (I imagine, I'm not reading them).
(Before anyone jumps on it, the "smile" comment was ill-advised, but separate to the above)
