we have a rule in our house - I don"t moan about the constant bloody soap on our TV every night, and she says not a word about my laptop being out every night. Best bit is, if I play the Sky Open, she always sits and watches with me on Sky865.
If I win live, I put 50% back into bankroll, and the other 50% into housekeeping. My online play is now all about trying to make £15k before end of 2009 to take my kids to DisneyWorld before my daughter finally loses her sight..... hence the missus has no problem with my 5 hours per night addiction.
