A triangle is very strong, and a ladder is essentially a triangle when it's opened and sitting on flat ground which provides the bottom plane.
A ladder with two weak or broken sides won't support much weight. A ladder with one weak or broken side won't support that weight either.
You have to be a strong individual first. The only marriages that can support their fair share of weight are those where both individuals are strong independently of each other.
You seem to have a lot of strength but like all of us we have broken parts as well. Work on that like mutatio said and you'll be ready for just about anything.
