Men have strange imagination, I had similar problem with a guy once he completely changed towards me I still remember the turning point in our relationship he never told me why either! it was sad because we had a good thing going. Don't worry it has less to do with you and more to do with him based on my experience.
OK back to the cards

There is a little secret that M has not disclosed to you. His intention is still to be friends or begin a friendship with you. He intends to share some new knowledge. Also he wants to support you in some way it seems as he realises that you're vulnerable. He will let you know the truth know about himself or he will ask you for some truth in the matter.
I picked one more card- got Letter
So he will communicate with you.
