To add, many of my friends and acquaintances had short parents even if they turned out around 176 cm so taller than their parents, who in almost 100% of cases were the same height (we're talking 173 cm or so, sometimes even less) and they seemed happy. No divorces as far as I heard.
You need to change your mindset and treating human relationships and sexuality as black and white canvas. Where everything is either a win or a loss, instead of being shades of grey, representing the amount of potential work you need to perform in order to have a chance to achieve your goal. I always found relationships to be of tertiary concern, because in the current economy we don't have much time to secure our livelihoods for when we are older or/if we'll need to escape for "reasons", this is where having money is a difference between life and death.
