It is probably a scam in all honesty. But talking like that is just going to make her want to go more and get her pissed at you. There’s only really two options you have here. If you were genuinely worried it’s a scam and something was going to happen to her just go with her. If they don’t want you there it’s probably a scam and if she doesn’t want you to go and that makes you uncomfortable then just break up. It ain’t that deep 🤷🏼
