I think that is a decision best made by you. I would like you to ask yourself if you would be doing something that is benefiting you or are you separating yourself to allow yourself to go back to bad habits? Are you in a place where you are strong enough to take care of yourself and reach out again if you need to? The reason I ask this is a few years ago I retreated not to regroup but to take obstructions (i.e. therapist who kept me accountable) out of the picture so I could allow myself to be unhealthy. I hope you stay safe either way.
