@dennisk20.stay away from her till she is really divorced.
@dennisk20 InventiveFarm5285 said it well. Keep your distance until her divorce is final. I know that can sometimes be hard when you care about someone. However, caring about her also means caring about her enough to not make things any more complicated or difficult for her as she goes through her divorce. You will need to give her time and space to heal from her divorce as well.
You do not want to be the "rebound" if you want the relationship to be sustainable. Two years is obviously a long-term investment in someone, but two years is also a very long time to wait for someone also.
You might need to consider whether you deserve more from a partner. You might need to consider whether you would want to wait another two years if it takes her another two years to get her divorce finalized. You may also need to consider what you will do if she does not ever finalize her divorce.
Divorces can be complex, painful, and messy. You do not want to be in the middle of that. Certainly, you can be there as her friend and someone she can talk to, but be careful about how involved you become emotionally.
No matter what you decide to do, take it slow.
