What is next after I-730 approval?

Hi, My wife has recently filed form I-730 after receiving her asylee's status and I am wondering if it is approved what are the next steps? My wife and I having disputes and it is likely that she might file for divorce. And if this is the case, how should I act. Can I still be able to go through the process of receiving my asylee's case without her? And what are the steps after I-730 is approved? Thank you in advance !
