She's very likely not in love with him and she's also very likely not scamming him. Neither of these things would go down in this way, with overt statements in open chat. What you were most likely seeing goes on all the time - it's just flirtation, or sweet talk with a dose of humor. Common stuff on sites.
On a different site, there's a model I know well and I'm her "knight," but it's just our thing; I'm her only knight and I don't actually perform any "knight" duties but I'll hang out in the room and stay out of the way. I see those "I'm so in love with you" comments all the time from members. Sometimes it's members who have only been there once and don't even know her. Sometimes it's guys who've been regulars for awhile. Usually, she'll say similar things right back to them. Whether the members mean it, or think they do, I don't know. But I doubt it. For most of them, it's just talk. For her, it's definitely just humor, or saying what they want to hear, or simply being nice. Sometimes it's even sarcasm! You're taking things WAY too literally.
If an actual relationship is going to develop, it's not going to be in front of you, in the open chat. It will be in private chat and then it will go offsite to Skype or Telegram or whatever. And exactly the same with a scam.
You said "they were sharing personal info." What kind of personal info? If you are talking about real names, contact info, that sort of stuff - no way this was happening in the open chat. Not on the model's part anyway. Not many models are going to take that kind of risk.
Maybe you were a scam victim, I'm not saying that isn't possible. It happens. But it seems like now you are reading into situations, looking for scammers everywhere.
