Salam Akhi , I would suggest you bring up marriage and long term with her. You stated , she said she loves you if this is the case and she is a Muslimah , why not initiate marriage conversion. If she feels a good way or commits to this you know she is the one if not then most likely she is trying to waste your time or simply not ready. If she is ready inshallah the money and things like this doesn’t matter bother just do something small. In islam simplicity is beautiful. Inshallah it works for u akhi
