TK, I think it's always important to make decisions from a place of strength not fear. Sometimes when we are fearful, we almost want to bring things to a conclusion, even if that conclusion isn't what we want - just to end the limbo.
But from what you post, you don't sound ready to make this decision and there is no need to decide anything before you go away.
Enjoy the space your trip brings. Do some new stuff, join a couple of things. Keep in touch with your kids and see how you feel. Sometimes doing nothing (other than working on you) is the best option I think.
Take care
