I found this post in one of the forums and fidn it quite true
(happen to mi thou) and funny
Problems with wife/gf playing:
1) Prone to getting in fights in general chat, I try to get her to
ignore the trolls.
2) Unable to see new content unless she is playing and seeing it as
well.
3) Having to fetch her things when shes in her groove and wont
leave the couch.
4) Dont ever do her a favor and rearrange her inventory, UNLESS she
asks, holy hell its a divorce in the making.
5) Dont move her characters.
6) Dont do her a favor and do a quest for her, she might take
offense.
7) Unable to level a character past her level.
Do
not finish an achievement before her, then you are a
"cheater".
