He told me last night he is going to California to do some work for his buddy for FREE--that is where the OW lives. I am planning a weekend with my kids and he said, well don't plan on me being here because I may have work to do in CA. Well, I saw the plane reservation he made on Sunday night. This is killing me but I am not letting it show. I am acting oblivious. I am sure he will ask me or my son to take him to the airport. Do I just ignore this knowing he is going to see her? Things have been pretty pleasant this week. Yesterday and today he sat in the morning and had coffee at the table with our 6 year old. He has told me to have good days. Does this mean anything? This weekend is just a hard thing to take. What is the right approach?
