A, That's quite an interesting phone call that you received. It appears that he's running of money and doesn't want to spend any more on the solicitors right now. Maybe he's trying to sweeten the pot for himself by wanting to meet w/you. Who knows at this point. But you know what? You won't know what is on his mind unless you actually sit down and speak w/him.
If I were in your shoes, I'd meet up w/him, but keep your mind in the business mode and listen to what he has to say. It's the only way that you will finally get some idea as to what he's thinking about. However, keep in mind, you will need to really, really listen to what he's saying for he will be mixing the true reason for the meeting up with a bunch of garbage when he's talking to you.
If you do not feel comfortable meeting w/him, then don't do it, But for myself, I'd be a bit curious to hear what he has to say and see him.
Good luck!
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.
