Lots of interesting ideas here.

Here's what I would do if I was ever partnered or the poor soul would marry me.

Have my YouTube history and recommendations filled with poker tutorials, poker stars and any related poker games.
Know poker games location. Or if friends are in on it then poker night.
Should know poker can go on for few hours if wife/partner wife ask why taking too long.
Withdrawn money for buy in etc.lts actually going to fs or massage shops.

If wife/partner ask me about winnings.
Well I'm not that good..
