Is it too soon to give up hope?

[2ndtimearoundCA]

I am not really sure how to define where I am at right now. We really haven't had any negative interactions since march. The big exception is that she canceled the Vegas trip two days before we were supposed to go without giving a reason. Still, I didn't get upset (as far as she knows). Anyway we have pretty minimal but positive interactions. And actually going out with her last week was probably the most positive interaction I have had with her since we split. It sort of feels like I am at the very very early stages of trying to build a new relationship and I don't really know what to do as far as how often to initiate contact or, when we are together, how to treat her so that I am not applying too much pressure but at the same time I am avoiding being just friends. Any suggestions would be greatly appreciated.
