Mizinamo is indeed authoritative. I give all credence to his/her answers, and always hope to see something from him/her when I'm puzzled. But I agree that this response seemed a bit cranky. I am far from fluent in German but i do happen to understand the sentence " Was bedeutet das?"
Literally 'Mein Mann' can translate as my man but if it is in German then 'Mein Mann' must be referring to My Husband. I don't think the English slang of 'my man' as in 'my old man' counts in German. It means My Husband in German just as 'Meine Frau' means My Wife not my woman. It is not about slang in other languages, it is about what that phrase means in German.
Many (some) people collect flowers and then place them into some kind of scrapbook. According to a site I found it is an addiction for some people.
