Ok, you want a girlfriend, great.
What do you actually want to DO with her?
Start doing those things on your own as much as possible.
Also, here is a trick:
When you walk to a destination, you don't spend the entire time staring at your feet, do you?
Find some goal that is a bit loftier, work toward that, and release the girlfriend goal... Make sure that the new goal is something that is really absorbing and consuming of your emotional energy, that you feel enthusiastic about.
The universe can chew on the girlfriend manifestation and you will be doing the obsessing over -something else-.
