DP has just announced they've signed up for a competitive triathlon later in the year and that it will require a huge amount of time commitment for training.
This means that a lot of evening and weekend child wrangling and general household shitwork will fall solely to me while they are out for hours training.
We both work full time, often one of us not getting home until 7pm several times a week. My argument is that DP simply does not have the lifestyle to accommodate elite athlete type training regimes. And I'm not willing to pick up all the slack just so they can say they've done a triathlon.
AIBU that there should have been some discussion with me about committing to this first? Rather than: "I'm training for a Very Important Triathlon so that I don't DIE young, so I'm just fucking off out for five hours"?
