I'm sure she loved having to phone, having to admit to her ex she need help, in a desperation, water does a lot of damage quickly, must of been a really horrible situation, lots of running around panicking, with a child there, a child you should really care a lot about, the child that is the part of the package you are marring into.
we get this a lot as part of our business we maintain properties, people get very frantic when water is appearing rapidly , even ones who know where their stopcocks are, forget in the chaos of the situation, then try to turn it the wrong way (GO TO YOUR STOP COCK DRAW AN ARROW WITH 'OFF' WRITTEN NEXT TO IT, you will thank me one day,I promise), or the stop cock will not turn, all cause totally capable people to have a helpless melt down.
sit down have a think how you would feel if the situation was reversed,
You at 5.15am water pouring everywhere, worrying about electric, frightened child,reduced to phoning ex,
and now fucking shitting yourself as you realise that your child's soon to be stepmother is insecure, selfish and resents her soon to be step son, what a nightmare.
