What is the logic for this?

A girl gets so possessive over you and immediately thinks female friends is cheating (Ones I had before meeting her and even the friend that brought us together.) but she goes and wants to flirt with other dudes or they flirt with her and she lets it happen. All the while she tells you she loves you and acts like she doesn't want to share you with anyone. And for more context. It was LDR with actual plans to meet ILR.
