I am currently married and we are happy. I am far from a loner, and your belief that it is impossible to have a successful marriage and family with this job is proof that your head is in the sand. It is proof that you live in denial. You are correct in the fact that there are pilots with failed marriages. But guess what...there are policemen, lawyers, doctors, construction workers, garbage men, grocery clerks, dentists, teachers, contractors, etc with failed marriages as well. They can also live in a world of denial. Perhaps the only way you deal with the fact that you left something you love is to continually talk down against it and subcontiously tell yourself that you don't miss it. Perhaps that is the only way you can deal with what you feel was a mistake. Everyones life is different, and that is something you cannot deny.
