Why do our lifestyle of no kids, debts or mortgage cause others to question our lives?

oKKKKK People! you tell me why alot of our social circle have difficulty accepting the way my partner and I decide to live our lives! I am a 35yr old female, I have worked since I was 22, since leaving college. My partner, he is 51 and he has worked 30yrs since leaving college. We met 10yrs ago and are co habiting this past 7yrs. We love each other very much but do not place any importance on marriage. Yes I respect peoples wish to get married but why do people not respect ours to not? The way i see it, is marriages break up too aswell as relationships and do not guarantee committment or that the man wont stray. We are both completely financially independant of each other. We are not together coz we 'have' to be, its because we 'want'. We have no debts or mortgages. We did not purchase property during the boom, we are in the long term rental market, a lovely country house where we WANT to live,not just some mundane semi that we can AFFORD. We live in a beautiful area, in a beautiful house. Sure we can be kicked out but then we just go rent another one! At the end of the day, what good is owning property if you cannot sleep at night because of a crippling mortgage. Both of us dont wish to have kids. We love kids but we like them to be someone elses! I see parenthood as a huge responsibilty morally and financially so i've decided not to go there. What i'm trying to say is why do people who have done all those things feel the need to riddle us with questions about our lives? We respect their decisions and dont ask why were they so stupid to have a load of kids and a huge mortgage? I think they are yes, but i never ask them why they done it. Thats their business! Same regarding our current state of unemployment. Its not ideal, we miss the salaries but we are doing fine, getting up late, long country walks, basking in the beautiful sunshine, losing weight and cooking wonderful food. Im even baking and doing art! I feel like i'e come into my own since i've got out of the 9 to 5 trap. Why are people so dissaproving?
