What I have found is that exit affairs are a “rare breed.” What I take from that is that there is not much information available about how to deal with them differently than other types of affairs. I should note that I have found that the exit affair is meant to be a way for the WS to “easily” exit a marriage.
I think when it comes to affairs, men tend to have more "cake eating" affairs, where they tend to not want to leave their wife/marriage, but what they want is just more easy sex with a readily available woman/en. Women, however, tend to have more "exit affairs," meaning that they're planning on leaving their M, and using the affair as a reason/excuse to do so, or basically setting up a plan b -- another man/relationship to jump right into.
These are generalizations, however, as there are plenty of people (unfortunately) on SI that have experienced the opposite -- serial cheating WW that don't want to divorce their BH and/or WH that set their AP/OW up and thrn just leave their BW with no warning.
I don't think there's necessarily anything easy about leaving a marriage -- there's paperwork, property to divvy up, lawyer fees, etc. Having an affair doesn't make any of that easier. If anything, it makes the whole situation much more hurtful/tense/acrimonious.
There's a common saying on SI, that you have to be prepared to lose your marriage to save it. Even if you think your WW is having an exit affair, the same saying holds, and that's because you can't control her. You can't make her come back to you. This is where infidelity advice almost sounds... hypocritical? That's not the right word, but I can't think of what I'm searching for right now... ironic? I digress.
There are things that you can do that make affairs easier to continue, and there are things you can do that make them more difficult, like exposure. Affairs tend to thrive in secrecy, and wither in the harsh light of day. It's easy for a WW to tell people that your relationship was over and she fell back in love with an old boyfriend. It's a lot harder to tell people that she cheated on her husband with an ex-boyfriend, because most people will agree that what she did is wrong, will judge her/them/their relationship, and will be wary of a cheater, because that means she's a liar and has questionable morals.
The only person you can control in this situation is yourself. You can tell your WW that you still love her, but that you will not share her with another man, and as such you're filing for divorce. Really, truly, honestly, that's all YOU can do.
She can either pull her head out of her ass and try to work on herself in IC and fix your M, or she can say, "k thnx bye," and keep seeing her AP. You can't make that choicr for her though. You can only choose if you're willing to wait around and keep infidelity in your life if you want to be plan b for maybe (likely, but not guaranteed) when their relationship implodes, or if you're going to move forward in your life and try to heal yourself. It sucks, because as much as you might still love your wife and want to remain married, there's literally nothing you can do to make her want to fight for your M.
Focus on you, your school work (you're in nursing school, close to graduating, right?), and just doing the best you can to heal. I know, it's easier said than done, but three people make a marriage explode. One isn't enough to fix it, you need TWO people who are all in, and it doesn't sound like your WW is interested in doing the work to repair your M right now, maybe not ever. Sorry h2w.
