Is It True?

No not true at all. Wait till she gets married. Most men find there sister annoying especially if they don’t do anything besides gossip and housework.

 

On second thoughts men like all women other than their wives so don't worry.

 

Hahaha they’ll only notice there wife if another man compliments his wife or if she loses interest in him just joking

I read your other post. Give him something to do and slowly build it up. He has some responsibility to you he’s supposed to look after your needs and not hers (SILs) she’s married now her husband should look after her.

Or start enjoying your life and don’t be too involved with her. If he talks about her switch topic to something that he needs his attention.
