I am wife and got a good career and conservative too, It is very very difficult (I guess will never can) to approve my husband friendship with his female colleague. I think most wife will agree with me.

Those girls out there who having "frienship/whatever they call it" please respect other women marriages, otherwise, it will be boomerang to those girls once they got married.

To Gtim : tell your friend if she feels something not right, then her feelings is right. She should talk to her husband calmly. Hope they can set the limit to have a long lasting marriage.
