Hello gents. Want some advice from non bias good people like yourselves.

Separated for 8 months, nearly finalized in divorce. Ex has a private new man the kids aren’t aware of but I am.

I in the last week began really connecting emotionally with a gal I know in text mostly. Then today we hung out for a few hours and the vibe got really strong. From her to me. I was so guarded but at the same time didn’t want to make that obvious so I rode a very fine line but probably was too flirty. When she hugged me goodbye it was with an extra squeeze and she said “oh shit” and gave me schoolgirl eyes like she was already falling. That “oh shit” is embedded in my head right now. And for some HORRIBLE reason it made me think about my STBXW. How long it had been since she looked at me like that. Sounded like that. But it made me find myself wanting her still too. And that really sucks because I’m just not fully over her. And I don’t feel it would be fair to start anything more than where it’s already at with this girl when she’s clearly into me and might be falling hard. Advice?
