Why are sisters jealous and insecure of their brother's wife but the same sisters are not jealous of their sister's husband?

Answer 1

One way of looking at things:Typically it is an older brother that is jealous. It is usually because that is his little sis and he was always the one to protect her. So if the husband does anything to her it usually the brother who will support her. He is basically giving up his role of protecting her all the time. But do note that it is really not jealousy its more just a feeling love and protection. Another viewpoint:It is not true or correct to say that most brothers are jealous of their sister's husband. Some are, some are not, and no one has counted to see which group is the most. Making that assumption is uncalled for.

Answer 2

It is not true to say that most sisters are jealous of their brother's relationships but most brothers are not jealous of their sister's relationships. So asking why they are is simply useless.

Of course some sisters are, some brothers are not; but some sisters are not and some brothers are. It is a matter of individual personalities.

Answer 3

This question makes unfounded assumptions about sisters' jealousies in connection with in-laws. Some sisters are jealous of their brother's wives, but some are not. Some sisters are not jealous of their sister's husbands, bot other are. It is misleading and incorrect to presume that all sisters are jealous of their brother's wife, etc.

Answer 4

The generalization implied in this question is not valid. Some women may feel insecure, etc., but there is no support for the assertion that most do.

Some women feel insecure around other women, as if it were a contest to be the prettiest, or smartest, or whatever else they value. It doesn't apply to men in the same way, so sisters husbands aren't seen as threatening.
