I'm so sorry for the loss of your brother, and for your current heartache and tears. You are certainly going through a lot right now.

Yes, I had someone do something similar to me - at least in terms of still pursuing contact after breaking up with me. He certainly is sending mixed signals. He wants contact, but not a relationship. He doesn't want you now, but he may later on. This is not fair to you. Yes, I would tell him to stop communicating with you. You can even unfriend him or block him on Facebook, if you want to. But he needs to let you heal and that involves no contact with him.

And yes, he's playing with you emotionally - even if it's unintentional, he is. I would not want to put up with that. It's just not fair to you.

I wish you healing and comfort. You don't need this, especially after the tragic loss of your brother.
