Was he your student and then you fell under his spell?
It is a spell you're under but you're only just realising it.
The good advice here is painful because you know yourself what you have to do but you want the happy ever after and so are in denial.
Op please start dreaming of a future where you are loved and cherished and respected. You are condemning yourself to a life of absolute misery every day you stay with this charming con artist, and you know it.
Start small by no longer giving him money and insisting on answers. Ask him why he asks you for money when a true muslim would never do that?
The secretive, distant,contemptuous, angry, controlling personality is 95% isn't it? But you only want to recall the lovely 5%. You are going to have to force yourself to fall out of love with him so forcing yourself to seeing his ugly side more often may just do the trick.
You don't want to break the spell because you'd feel an absolute fool that you have allowed yourself to be taken for such a ride, invested so much in him and it's really embarrassing isn't it?
You sound professionally competent but emotionally damaged, a perfect combination to be a victim of such a calculating, devious and dishonest con artist.
The spell is breaking though, op, thank god. Please do what you have to do and don't look back. Be strong. No decent man, muslim or otherwise would treat you as appallingly as this.
I believe in you though op, it doesn't matter you have made the biggest mistake of your life in investing time in this man. You can get out of it, you are only in your 40s and your future is bright once you make the moves you know you have to make.
Good luck op x
