Moon, I am so sorry for how you have been treated
Something similar happened to me I don't know exactly how you feel but I know how I felt- like my world was over.
Please don't blame yourself for his behaviour, it was not your fault, he chose to be unfaithful, your actions didn't make the decision, he did.
I know you will think if all the bad things you did and said, and this is normal but you are punishing yourself.
I know it's hard to see any light now but maybe you had a lucky escape from him. He isn't accepting any responsibility or giving you any explanation and you deserve more than that. At least a phone call or to talk in person. It's a cold and callous way to deal with things, my ex did the same, broke up, never admitted her affairs and totally cut me off after six years but it wasn't about me it was her. She couldn't face what she had done so blocked it out of her mind and convinced herself she did nothing wrong.
I feel you deserve so much more in a relationship. Do you have good friends right now? I didn't see any mention of friends in your post and it is so important to keep your friends when you enter a relationship because if it ends and it was only the two of you, it's devastating and you have a hard job of rebuilding your life
I am glad you t is very understanding and supportive as you deserve this right now! Please be safe and look after you x
