ok here is what you need to do G.
start being an even greater super nicER guy. Buy her flowers everyother day, take her out, buy her stuff, call her every 10 min, actually listen to her when she talks, refresh to her that you have big hopes and dreams in life and big plans..etc, be very caring and extra loving to her, go to church more, stop swearing, stop drinking, just smother her all the time like you have ZERO LIFE..etc..etc
......keep all this up for about 3-4 weeks........then she'll tell you she needs space or something. Act like you are not understanding why...etc. Then walk out the door with your head down (and a devilish smirk on your face)..and there u go.
