IMO having a "girlfriend" is something more than just having fun, meeting new ladies and casually dating.

Is your GF aware of your legal case, the custody issue and the fact you are still married? I hope so. Have you been upfront with her that you are still emotionally attached to your W?

I find it odd you call your GF "OW". Be upfront with her about where you are at or else you might really hurt her. We all have to start somewhere, I understand that. Does your GF know you are still holding out hope to reconcile with your W?

What does your attny say about you having a GF?
