Yes you do, you have your time when you should be doing other things - be it working on yourself, or out with other friends/girls. What's the point in spending time with this girl if nothing is ever going to happen? which is what YOU want.
This is a symptom of the problems I wrote about earlier in the thread, that you don't have enough options and that makes you over analyse non interested girls and waste lots of time.
She's already made the point that shes not interested, so there's not much point to this. If you are comfortable just being friends and hanging out (maybe trying to meet new girls through her?) then that's fine, but I don't think that is what you are doing here.
Stop wasting your precious time, and go meet other people.
