Hi Yoyo, Let me just say I think you are a smart cookie. He is being clear he is worried about money. If you think he is "playing nice" to protect his interests, then you are probably right.
Sara kicks ass (see above). You should listen to her, but you already know that
You have such great advice from all our friends here. I don't have more to add other than if you think the rewards outweigh the risks, then do so, knowing you have your eyes wide open and knowing the effort it's going to take to make it work.
And as they say, "trust but verify."
I am keeping you in my thoughts and prayers. Yoyo.
