Buxom, I'm so sorry that you are having a difficult time. Take a moment and just breathe! I would suggest that if he pushes to have a talk, I would sit and listen to what he has to say. Allow him to completely finish his conversation and if there are things that he says you know aren't true or he sounds very unhappy, I would start out by saying "H, I'm sorry you feel that way". If he brings up the subject of divorce, be honest and say "H, I'm sorry you feel that way. If a divorce is what you want, then I'm not going to stand in your way of getting one." If he wants to discuss splitting up assets, etc., stay "H, I need some time to think about all of this and I will let you know what my thoughts are at a later time." Keep things simple because if you start so show emotion, he's going to react to it and normally not in a positive way.
Since you are a very new member of the group, I wanted to advise you to stick to one thread until you've reached 100 postings/replies. Your other thread has less than 40 postings/replies. The reason we are asked to stick to one thread at a time is because we need to be able to post to one thread at a time and when there are multiple threads on the forum, we, the readers, will not know which one to post to because they are all active. Also, multiple threads doesn't allow us to keep up w/your situation, i.e., just as you will have a difficult time referring back to postings to see your progress. Also, you can change your subject line within a thread at any time. Cadet will most likely merge your two threads together.
For now, breathe! Try to stay calm. His talk may be happen or it could be about something else, i.e., something minor, but is important to him.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
