Why is it that relationships are seemingly impossible?

You're single, you have none of the anxiety(ies) that always stem(s) from a relationship (can I say if you're a good person, the bank I owe money to has just shrugged) you don't have to worry about disaproval if you buy something and you have your own body back, so you feel fed up and get involved with the next person who wants you but then their expectation, they're with you, lucky for them, isn't met by the fact that they are with you but you are afraid of not having anxiety and having the freedom to not be accountable, meanwhile you are accused (falsely) of all manner of bs because you don't meet the idea of perfection that you are clearly with but it only takes years for you to lose your entire sense of duty, responsibility and working towards contentment, which you can look in the mirror and say to yourself, at any time, I have myself and I'm balanced enough to see perfection in the context of action, not in conforming or, it's just give and take and Sex And The City (a made up story about a writer, a writer writing about a writer, how lazy is that?) belttles almlst every human experience into some kind of category. I'm not saying relationships shouldn't be over or under valued slightly but why do the demands always seem to increase (if you end up getting dumped it's stated, 'life isn't a test.', my belated retort is that no one is born knowing how to tie their shoelaces and so I've learnt I've been bullied (crushed is probably a better word) into agreeing with fraud because I never calculated cruelty could be extended beyond decent limits, people hate decency, is that why soo much self love is apparent within those who we tell ourselves we desire) Self desire and balance doesn't seem to fit the bullying and forever warning media, is it all for our own good?
