To me seems like Aliantha and DucksNuts are right: maybe she will feel not good wondering around the same flat with the new (let's hope) and the ex... but I think you can manage it if she wants, being around or at her place, and not at yours... I mean, now she has to be well, then think about new person, and if you two date then you'll decide if it's worthy! but I think so seeing what you write!
good luck
