Dear Sunshine37:
You wrote that you were selfish with this friend, enjoyed the frequent texting, but when he texted you less because he was tired and worn out, you accused him of lying, that is, that he was not tired and worn out. There were a few arguments and the connection ended. Did I understand correctly?
If so, it is understandable that he stopped texting and communicating with you- he got tired and when he was tired you accused him of lying and argued with him, removing any motivation he had before to keep contact.
More of your thoughts/ feelings?
