I agreed with him and told him that I was sad too that he was leaving, but told him that I wished him all the best on his journey and that I was sure that he would be fine etc. He simply replied with "That's true..."
A week later and he's started posting about how terrible of a girlfriend I was, how his life will be so much better without me and that he's moved on. I haven't responded to anything and just ignored the whole ordeal.
But why is he angry at me when he tells me that he's leaving? I can't exactly do anything for him considering the fact, that he dumped me.
