Hi Rabbit,
Well you know I'm pretty knew to all this, so take this for what it is worth... but I would think you "act as if" he is telling you the truth and will be coming back... but you do so with clear boundaries in place for you. so, then if he violates those boundaries in any way or there is further cake eating in any way... you go back to the GALing, pull back contact etc. And keep doing what you need to in order to maintain your PMA in the meantime.... Just my 2 cents...
