I think it's a really big thing that he's come and met your friends - especially as he might presume you've spoken to your friends a lot more recently and fully about what it in your mind and heart and they might have an opinion about him. Not saying that's true - but I can imagine it might be in his mind, and might be a bit of a facing for him. It is a positive sign.
I have a friend whose husband gets a bit critical and controlling (not in an abusive way, just in a nit-picky, moany type of way) when he's stressed. She deals with it by very mildly and affectionately making fun of him. Her point is made, but she's light hearted and affectionate about it and he can take a joke and is aware he gets a bit moany and critical when he's stressed so is willing to accept that gentle reminder from her.
