Surely ‘up to our discretion’ is what you mean; i.e. ones own judgement? ‘Up to your indiscretion’ makes no sense, it is not anything a native speaker would say (unless an attempt at some highly ironic or witty reverse-meaning play on words). I’d suggest 99.99%+ of people would not understand what you meant. In common usage ‘indiscretion’ is -> accidently calling your boss a wan***, then realising he’s standing right behind you and heard it - Or getting completely pi****, and trying to chat up your girlfriends mother, while your girlfriend has gone for a quick shower.
This sounds like something out of Charles Dickens, or Oliver Twist! ‘I say good sir, one finds oneself coerced into believing what one might otherwise have preferred not to have to’.however, I will be obliged to believe that the following assertion is true."
You're trying to 'over-ponce' your English, and you're beyond your limits. The result is you're misusing 'long words', and IMHO it just looks rather affected, and undermines the whole.
