Sparklie, I am another other half - I ain't complaining about my boyfriends paintballing.
My point was that if a partner is not happy about time spent on paintballing, then they should get their own thing going - preferably as expensive, with shiny pieces of gear, and that takes up the weekend - have the rest of the week for coupley things.
If you don't want to join them, beat them!
And Crom, involving the marker in your love life - maybe not. Think about the hygeine...
