Low, cloud

After a day at a Buddhist retreat I am exhausted.
As I returned home, I bought a basketball for my home stay student to play with, 2 camping chairs for the open air concert on Sunday,then I bought chips for tea. As soon as we'd eaten , we went out to the MUGA, he played while I went shopping.

During the day I had a text conversation with ex. He thinks working on his happiness and spiritual life will help me somehow!! I just want him to move away and leave me to live my life here, in peace. It's not going to happen as he has no sense of the wrong he did, and therefore no reason to feel he should take action to help. I don't understand the Buddhist teachings on this one.
