Thought work around my ex husband

I was doing well with my thoughts about my ex husband. We were on friendly terms which was helping me process the grief of our lost marriage. His father just passed away and I went to the funeral last Friday and lots of feelings came up for me. 50/50 kinds of feelings. Reasons I was glad to no longer be with him and reasons I was sad to not be. I think he wants to see me again, be with me in some capacity and I don’t know how I feel about that. I want to make a decision and would like some help in how best to do that.
