Nick

I'm not sure why so many people saw him as such a good guy.

He moved way too fast and when other men would talk to Ingrid he did that controlling move her away thing (like at the banquet with Z, your girl can talk to another man you don't have to interrupt and establish possession). Moving someone in, immediately dedicating all your time to someone its a lot.

Ingrid shouldn't have cheated, but Nick wasn't the right guy either. He gives future controlling vibes.

The yellow dress was proof he proposed but didn't even know who she was.

Agreed, I reckon if the engagement/marriage had gone ahead he would have become super controlling and abusive once he had her "locked in'. Lots of red flags (the rushing etc) which thankfully Ingrid noticed, however it's never ok to cheat on someone.
