I agree with Was2Sad. And your own instinct not to rush things. I don't doubt that your h is sincere in wanting to return, and is very very sorry. BUT I am not convinced he has resolved any of his underlying issues. However, many people never do, and manage to keep themselves afloat.
The best buddies sounds like a good scenario to me, until and if you want more.
Maybe it is time to think again about the dynamic of your marriage/relationship and what made it work. Who put the effort in and where? This will be a new relationship for you both, even if it remains a friendship, and perhaps you might want to review old patterns that you would want to avoid this time around . . .
In my growing friendship with my xh I am much more affirming of him, because I recognise now just how fragile his ego is. But I do not want to prop him up or help him like I realise I used to. Unhealthy for me and for him. I accept who he is and celebrate the positive changes in him. I think he has been through h*ll, and is far from out of the dark place.
