I can't understand the meaning of жена-собственница
.
У меня жена-собственница! Хорошо ли это?
Жена-собственница is an extremely possessive, jealous wife. Собственник/собственница can describe a wife, husband, girlfriend or boyfriend. Also, it's sometimes used to describe a mother who has become overly possessive of her son.
I was going o say "authoritarian wife" but googling hints that this term has not that subtle sexual connotation that by no means applicable for жена-собственница
. So it's about a wife who's quite annoying it her attempts to over control, most likely quite jealous. It's not gender biased though, the masculine собственник
uses as much frequently.
