People who have been in abusive relationships can spot them a mile away, and that's what a ton of people here have done.

He's emotionally manipulative, he never takes responsibility for his actions, he always blames others, he has an anger problem, he doesn't get along with ANY of the other guys. Literally every single one of those is w colossal red flag.

Thinking he's just "in love" or "crazy about her" is EXACTLY how people end up getting hurt and abused in relationships. For your sake, I hope you read up on red flags, becaude Luke is basically wearing a giant sign around his neck in every single scene showing how he is, and that's obvious to people who, sadly, have experience with those people.
