"I'm not sure that he will come back if I'm honest."

If he can get everyone on his side he will say he wants to return even though he's not quite there yet. Here he means he wants you on his side. You could gradually influence him into thinking everyone is on his side though you shouldn't say you are. If you do it will destroy his motive.

The majority of these reconnection's fail. The reasons are two fold. First, being on his side means avoiding all planning and doing as little as possible in his presence. It means admiring him full stop. As for the second it means letting him have his own way, gritting your teeth and smiling through it. You ain't going to do either of these. Especially if he decides to buy something you cannot afford. To get your own way, you need to play on his charm and be more charming than him. If you play on his language and try to twist his words you will lose. Whatever you say hasn't got to be your last word. You need to always think upon it. I'm unsure how long you would need to keep this up. Certainly for a good few weeks.
