I am glad it is working out.
It is a shame alot of people these days say just dump her, or just give up. Love isn't easy to find these days...if you have it, hold onto to it!!

Excuse me, but real game is ultimately being completely truthful (arguably). Every PUA has their own style, and mine is generally very honesty-centered.
For example, I almost never use "canned openers" except for the ones I made for myself from real experiences I've had... but that's besides the point.
Just make sure you aren't being needy/desperate here, and be emotionally prepared to "move on" and accept it, even though youve been "chasing her" for a long time. Since you have a window of opportunity here for New Years, you may want to invite her to a function as your date. Don't go to someplace SHE invites YOU to. Take charge and bring her into YOUR reality.

Sounds to me she's kinda brushing you off relationship wise, but still wants your friendship. If she isn't including you in holiday things and ESPECIALLY New Years - she's definitely closing the door. I'd be nice, casually tell her all about the GREAT plans you've made and just let her go. If she can't be honest with you and tell you straight up how she feels, she'll only hurt you later on.
