Hi Jane, I'd go with your 2nd option, but tell him, just as he is protecting his interests by keeping you out of the house, you are also protecting your interests (the car) by making other arrangements.
I'd also include that you'd like to be able to discuss this with him face-to-face or with a neutral 3rd party but as you said in your post, you do not want a hostile situation to arise. And that you are patiently waiting until he is in a better emotional position to discuss it.
His behaviour of not letting you into the house to get your things, putting what you asked for in bags by the curb, etc has lead you to believe that if he got the car you would not get it back. BTW.. are both cars in both yours & his, names or are they registered only in yours or only in his? this is just my opinion... I am not a lawyer, nor do I play one on TV
