There are nice men out there
I'm lucky enough to have one. I'm not looking to paint all men as abusers at all. My partner and I play fight plenty. We've never physically chastised each other in anger because of behaviour we didn't like though, because that's crossing a line.
Either he's a cracking actor (which could explain the second video but I'd wonder why the hell he'd think it's a good idea to act like he's that angry), or that shove is a genuine reflex because he's pissed off she's speaking over him. That's not nice guy behaviour. Nice guys don't elbow their partners.
The slap isn't good either. I don't think anyone would say it is.
No, we can't say 'MB is a horrible abuser' from a few clips and I wouldn't claim to be able to, but those interactions don't look healthy, and they've been posted for the world to see so are going to invite questioning as to the dynamics in their relationship.
If you think they're both smiling and laughing convincingly you need to reassess your ability to read social cues though. In the first clip her eyes momentarily slip from focus on the camera while he's pulling her in (after she resists the first time he pulls on her arm). That doesn't generally happen when you're being cuddled and you want to be. It does happen, for example, when someone is distancing them self from a situation though. Then he keeps her in position physically and her smile drops completely from her eyes, and almost all from her mouth. That's not the expression of a happy person, particularly one on camera who is supposed to be 'presenting'.
