Most Helpful Guy
girls control sex, guys control relationships... sometimes guys get into relationships with women they truly want to commit to, other times its for sex and after a while it gets boring and they dont want to hurt the girl and make her feel like she was only used for sex so they start acting like bad bfs hoping she will break up.

Here's my opinion but keep in mind I'm not a guy-
Guys don't usually like talking about their feelings. That includes feelings of unhappiness or even sometimes love. They won't say somethings wrong, instead they act out like something is wrong assuming the girl will get the hint.
It also makes them look like the bad guy if they break up with the girl.
