I guess some people are just too lazy to change their information. Its not like they are actually on the look out.
Maybe your brother is friends with her now and maybe your bhabi too knows her or maybe some wives trust their husbands way too much to even imagine they would care for some one else than them.
He probably doesn’t trust you, thinks that you’re going to go tell your parents or his wife. Or he just doesn’t like you.
I don’t get how a wife can be ok with her husband pretending that he’s single and flirting around. Open relationship? Most guys that I know of over here, change their FB status immediately after getting engaged.
Infact i think the pakistani women are more possesive unlike the western women. They would actually be more concerned about what their hubby’s do or dont do on the net or elsewhere too.
