I'm married to a big loafer...........?

All i asked was that he goes out and gets me a cake of chocolate so i can lie and watch the telly and eat it. His backside hasn't moved off the sofa all night. He's a lazy article. He's been working a 12 hour shift and just expects me to run about after him. I've been out all day with big Margaret from up the stairs at the Bingo then the pub. I've had a busy day. What should i do to get rid of him so i can get some peace and quiet? Bearing in mind that he's been banned from the pub because of that incident with the celery..............
