I would keep it friends for a while yet.
The "void" is it because she actually misses you? Or, is it because she hasn't found someone else?
Besides the drinking issues and related problems. How was the relationship otherwise? What were the "boundaries of friendship" she crossed? was she asking personal questions about things that are none of her business?
Congratulations with your progress so far it's a big step for you.
A big part of your decision should be in regards to your drinking. Now this is coming from a dry alcoholic, who had a huge and I mean huge drinking problem. But I've been clean 13 1/2 years. :-)
Because there were some problems in the relationship, you don't want to put yourself in a position that may cause you to start drinking again. I'm not down playing your progress because it is commendable, but 6ish weeks is not a big amount of time. Why did you get sober? Did you decide I need to get my sh*t together? Or was it more for her?
You don't need to answer these questions here. These are things you should ask yourself.
Definitely keep the friendship. But I'd give it 2 or 3 more months before deciding whether you want to give the relationship another try.
