Your business partnership has gone south, which means that you need to treat the ending of the partnership as business and business only. Keep your texts to business and/or emergencies. Your h is being nice at the moment because he is getting what he wants and he knows that he has to play this game in order to keep you on the line and easier to deal with. I wouldn't be texting w/him unless it concerns coming to the house to pick his stuff up, bill discussions and/or financial stuff (which if it involves lifting the order, etc., refer him to your lawyer).
Trust me, he knows that he'll get more with honey than with vinegar. Stick to the business at hand. He can't miss you if you are responding to non-business texts.
Keep the focus on you as much as possible. Put a rubber band on your wrist and each time you are tempted to say something to him in person or text him, snap that band. The sting will stop you from doing whatever you are thinking about saying or doing.
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.
