You are in no shape to date at this stage. You are still emotionally tied to STBX. Embrace your "aloneness" and get comfortable with that state of mind. When I felt lonely, I itched to reach out and date. I knew it was for the wrong reasons so I fought to stay off the slippery slope.
I am glad for the choices I've made. Once I arrived at a stage where I was "perfectly" fine with being alone, it was when I started to date again. I dated from a position of "yeah, let's explore" instead of "ugh, I am so lonely...I am so needy." See?
You will find a healthy woman in time. Trust the process.
