I had done Mutaa’ with a guy to get to know him better for permanent marriage. But I never met him in person.
And now after two months I don’t think we are compatible for each other and would like a divorce.
But right now I am in my hayd. Can i still get divorced as I never actually even met him in person?

This is a condition for a permanent marriage not a temporary. A temporary marriage can be ended when the women is in Haydh. Also, there is no official divorce (with two witnesses and so on). He simply says to you I gift you the remaining portion of the Aqed and it will end.
