A girl I've been talking to recently has been giving me pretty low interest levels. I asked her to hang out last week and she gave me some BS excuse so I just said ok well let me know whenever is good for you. I've been ignoring her texts the past couple days and she just texted me saying she's free tomorrow night. It would probably be a good idea to say no cause she usually gives me some excuse when I ask her to hang out. But then again she's tough to get out so who knows when I'll get another chance like this. What do I do?
