change back?

As is often the case, when we try to make changes for the positive, we get the "change back push-back". For me, this has ended more than a few relationships... "sorry, i liked you the unhealthy way you used to be" wasn't precisely how it was put, but it was close. So, when I get any resistance, I feel goodbye coming on. I guess that's why sometimes I get defensive. I'm so scared people are going to leave me. Of course, if I'm that petrified of it, they will. We will be left one way or the other, by death, or by people leaving. It's a fact.
