Dear aidan:
I don’t have experience dating a clown. Regarding you hating “fake, two faced people”, and suspecting this woman is that, why not ask her questions, straight forward, clear and direct questions so to get to know her, what motivates her, what does she value as important in her life and so forth?
That way you will find out if she is honest, one-faced with you, so to speak, as you are with her.
