I agree with @georgia, you could do either. I would do what feels thest way for you, whether to gether or separately.
She recommended some great ideas for doing so as well!
We have some cord cutting spells too around also if another type sounds vetter for the situation as well:
→ Magickal Binding 
→ Cord Cutting Spell
→ Cutting Ties Spell
→ Banishing Spells
→ Simple Freezer Spell
