DOES ANYONE ELSE FIND THIS TO BE WEIRD??

So I have a friend, more of an acquaintance nowadays, who I met in the restaurant industry when I was 16. We’ll call him “Calvin” for the sake of the story. Calvin is 45+ now (I’m 29) and I see him very rarely at some mutual friends’ parties and events. He’s always been a player and a ladies’ man, and in my younger years I’ve seen him touch and caress and try to seduce at least a dozen adult women at bars, with their consent, in the obvious hopes of having sex with them. He’s even asked me for nudes at times (when I was 18+ and a full fledged adult) which I always said no to. All of that backstory aside, I met his current girlfriend a handful of times and she’s very sweet but she’s a divorcee and has three children that she recently moved into his house. She has a daughter that is 14, a daughter that is about 10, and a son that is about 6. Tonight I was scrolling through Instagram and I saw Calvin’s girlfriend post on her stories. They’re clearly having a Super Bowl party at their house and there are a bunch of people in the background. The first post was a video with the caption, “Find yourself a boyfriend that loves your kids like this❤️❤️❤️” and the video was of Calvin and the girlfriend’s 14 year old daughter sitting on the couch. The 14 year old is wearing a small tank top, no bra, and pajama pants. Calvin was slowly rubbing and massaging the 14 year old’s bare neck and then trailed his fingers upwards into her hairline and started playing with her hair. The second post to the Instagram stories was a photo of the 14 year old laying on Calvin’s chest with a glazed over, blank look in her eye while Calvin continued to play with her hair.

I know that some “families” are more affectionate and touchy-feely than others, but this whole chain of events just struck me as SO wrong and so off. I come from a very loving, affectionate family and extended family but I have NEVER ever, ever been touched like that even by my own father, aside from maybe when I was a very small child that needed to be soothed to sleep, let alone by any other blood relatives. And had there been a boyfriend in my mom’s life (which there wasn’t, she’s still married to my dad) I CERTAINLY wouldn’t have been being rubbed and caressed by said boyfriend at 14. Am I wrong for thinking that something is gravely wrong with this whole scenario?? As a new mom, my motherly instinct is telling me that 14 year old girl is in danger. Does anyone here think that it would be acceptable for their 45+ year old boyfriend to be rubbing and caressing their 14 year old daughter in the manner I described?? I literally want someone to tell me that I’m crazy because I just don’t want to believe my own gut reaction in this instance. I am so disturbed. Please let me know your thoughts. And if you think something is wrong here like I do, I’d appreciate any advice as to what I can do about it.
