My sister is due to get married to her fiancé next August and for the previous two years he has lived at our house.

The plan is for them to move out after the wedding but personally I don't see this happening. Its not that I'm a nasty person just that my home life has been a nightmare since his arrival. He is also a bloody liberty taker. I just can't see there departure being a swift one after the joyous day!

Reason being is that they have it too easy at our house and have no worries. Ok they do pay rent but it has got to the stage where I can't be in the same room as him!

Will we finally be rid of this annoyance or should I be prepared for the long haul?

The way I see it, your family is in for the long haul unless you get together with the other family members and talk it out. You are not alone in your feelings.
