I feel like leaving her

Me and a girl I’m talking to are planning to take the next step and get married. she’s a tiktoker and she lip syncing songs and posts thirst trap videos. We talked about it and she says that she’s just having fun and I can anytime check her acc that she’s not entertaining anyone. I’m thinking about ghosting her and never talk to her again but I’m waiting to move out since knows where I live. Any misunderstanding she’s at our doorstep. What should I do?
