Urgent- the questions is about divorce

Asalamualaikum hope you are well , My wife has been abusing me for months, yesterday i said to her “you’re” and then the word. I then took her back saying “I take you back as my wife” . I wanna know what’s the process, she was on her period or just about to finish, this is the only time it has or ever happened, do I need to say specific wording or is what I said sufficient and just checking do I also need to be intimate with her asap. Thank you for your time May Allah reward you
