have you asked you lovely wife to join reading the thread the board has to offer. there is a lot of info in/on here. maybe if she see the responds from the ladies on here. just maybe she will have a different feeling about it all.
BUT. please don't make her do so. let her come in/on when she wants to.
the best thing you can do is... talk to her about it. but do not push her.. if you do... she will hate it even more.
i hope this can help.
