She still says she doesn't know what or who she wants
Right. File. Now. Bollocks to waiting around for her to make up her mind. Free yourself. You are worth more than that and if you don't act like it she sure as hell won't realise it. you deserve to be with someone that wants you and you alone with no doubt in their mind. You deserve better.
If the emotional part of you still wants her then this is also the best chance at shocking her into realising what she is missing, but either way file immediately and start the process. it can always be stopped if things change dramatically.
