I am sorry this happened to you. I think he was breaking up with you. I pulled cards and get 6 of cups, Hermit and Empress reversed. I have a feeling he was becoming more distant and you didn't know how to TALK to him about it. But for him to "Ghost" you--just stop speaking to you--is so very rude. I am not sure what the future WILL be--but I would give up on him and find someone BETTER and more honest for you.
Your boyfriend ghosted you. He is afraid to face your questions and fear. He knows what he is doing is wrong and that’s why he cannot face you. He will not change this path, even though he may waver in a weak moment. This is about his weakness, not yours.
I feel that your boyfriend has a difficult time at expressing negative emotions to people close to him. Even if it is not a negative thing about you ( and it's not) Your a strong person and he doesn't want to seem Wait it out and all will be fine:)
