To the Dil bashers.......
It's not the DILs being "bashed" here!
Trisher has very simply put forward some practical suggestions, as others attempted to do earlier, but littlepig still seems to feel the need to blame her in-laws for every thing. She asked for advice and has had a range of suggestions including getting DH on side, being polite but firm regarding dates, involving them in her domestic arrangements, carrying on with ye normal routine etc.
Littlepig, I am glad you agree breaching someone's privacy by nosing through their iPad was wrong, but not for the reasons you state. Simply because it is the height of bad manners, if you can't see that I don't know how you can whinge at your in-laws' manners.
So on one thread you moan about your FIL, on the other, your MIL, the message is clear. You don't like them, you don't want to have them stay with you, well if you go on like this, they should get the message. Pity you and your DH were not adult enough to manage the situation in a more mature and civilised manner.
