To be fair, I don't think he's actually a bad dude either. Again, flawed, but reasonably well intentioned.

The "worst" thing they did was definitely developing feelings while she's engaged to Roy, but most of that was the nature of working in close proximity. It's inherently different than sneaking around to spend "platonic" time together for a bunch of hours by choice. He had feelings, but mostly didn't cross the line. I don't think he's a terrible person for laying his feelings on the line when she's engaged to someone he doesn't like either. Actually married is the line where it moves to completely not OK.

But yeah, the whole end thing really wasn't anyone being awful. He unilaterally made some decisions that should have been a partnership, and he was wrong to put that much stress on her without talking to her and hearing her. Because they had kids, primarily. But he did recognize that and came back and made the commitment to their family. Then, once she had time to actually breathe again, she was ready to take the leap with him.

That was longer than I meant it to be again lol. But I was surprised to hear the take (and that it was more popular than I'd guess) because it genuinely never occurred to me. She was in pretty deep and he was lashing out from the stress of the situation before she even vocalized her problems with it. (At least from what we see.)
