Honey, Im Home. Honey?

Is there really not enough room in the box of life to have it all? I was just thinking in my life, whenever I began to sort myself out and try to get things in order, be it with a new job or something else massively changing in my life, my relationships always seem to suffer and often drift apart, I remember a couple of years ago, when I was with someone for about 14 months, 8 of which I didn't even want to be there, I felt like I was trapped and actually needed a solid way out, and when I started a new job, where the contact grew shorter and more limited as the days went by, the relationship soon ended and I was free, I then thought about it after it ended, of the job giving me the opportunity to swiftly escape, to have a scapegoat rather than explain in totality of why it really ended, but then I saw it happening again, greeted with the potential of a new career path, a new set of expectations of a promising new future for me, and my relationship suffers again, so thinking on that, did my last relationship end because the new job gave me the opportunity to leave?, or realistically, did the new job and the focuses on myself for a change, automatically make my personal life suffer and rip the relationship apart? But then again why is it only that your relationships that suffer? Why not your friendships? Why not your family life? Is it that we only have a certain space in our brains for one or the other, our friends and family are forever fixed in their sections, but the potential of love or a career always hang in the balance, fighting it out where one always wins and the other loses, is it really impossible to come home after a busy day of work and find the one you care for, greeting you at the door? Or is it that to be in the real movie romance, we have to live in poverty?
