A different vibe...
I'm a father and whether your husband is a 'good man' or not I can have a pretty good guess at what might be happening.
Little girls turn 11 and suddenly they are no longer 'little girls'. They get bumps in their jumpers and it becomes obvious to their fathers that they will soon be (blink of an eye) young women.
Look at the endless number of threads on here about mothers struggling to cope with teenage sons who they can't seem to understand - who they seem to endlessly bathe with - it's not easy when your kids suddenly stop actually being kids.
Some men cope better with this than others. Some women too. My daughter is almost 15 and she's got a (sort of) boyfriend, she has a few drinks now and then, she goes to parties where a LOT of temptation is on offer and I (hope) that I cope with it pretty well - but I worry about her !!!! She's my little girl after all - only she's Not anymore - and that is an adjustment...
Your husband can see his 'little girl' growing into a young woman and he probably wants to make as sure as he can that she stays on the 'straight and narrow' - doesn't end up pregnant at 15 and shot gun married to the farmers lad down the lane... Essentially this is all well intentioned but it may be that he is boiling up a load of stuff inside him that he's massively overly worrying about for no reason. All this stuff is (for no fault of hers) because of her and he's over focusing on her.
Not good - but normal.
However, I have to echo the "he may not talk to me for a few days" thing - that can't be healthy in any family...
Maybe talk to him about the reality of growing up as a girl (he will know NOTHING about this) and pre-warn him that actually girls like sex, like drinking, like flirting , like parties, are not made of glass and paper and that he WILL have to cope with it all in the near future as little girl inevitably becomes young woman in 2018.
I hope he truly is a 'good man' but if he's going to be a good father to your daughter he's going to have to give her some space to grow in all directions.
He can be her best mate at home, he can be her "go to guy' for help and advice on so many things. Perhaps you, or someone you know just needs to tell him to learn to let go a bit...
