Is she really interest when make tentative plans and she never confirms, but seems sincerely interested when asked?

We been talking for 2 months, been on 6 dates, to include an overnight trip. She says she has a busy schedule, but if I want to do something that I need to ask first before, friends and family. So I ask her a month out to do some thing. She says; "Let me check my calendar and get back to you." She makes no move to pull her phone out. Three days go by and I inquire about it once again and she gives the same answer, without providing any additional details, explanations or update. You ask what calendar do you need to check? Is there a calendar at home hanging on the wall or on your work computer? If not interest its okay to just say no. She says she's interested, she just needs to check at work... that was three days ago and she hasn't mentioned it or provide any details.

Is this women sincerely interested or is this a brush off in disguise?

Should I even bother to ask a third time?
