You will meet people you know at the store. Some will avert their gaze, some will change course, and some ( like me) will still acknowledge you. Family goes the full spectrum from outright treating you as dead, lessening contact, and maintaining contact in private. If in the same household you may be excluded from prayers before meals, discussions, and maybe nagged at to " come back"
You can leave for good, do what is needed to get back in then fade, or go back. No one can tell you what to do, but some will try. We dont know the details, some DFs are for reasons even the world can understand ( adultery), others are just kangaroo court reasons and there are shades in all them. Do not forget to keep living your own life
