It sounds like this was all for the best. But right ow, you probably feel like your world is falling apart. I've been there, done that, and am still alive and well to tell the tale.
I can only speak for myself, but my divorce process was incredibly time consuming, financially and emotionally draining. I was in grad school at the time, and fortunately had very understanding professors. I needed to take 2 Incompletes (in separate semesters, again emphasizing the time it took for everything to be settled- child support, custody and actual divorce). I did have supportive family members (although none who have been through a divorce, nor through a graduate nursing program).
My point is, you may have to take some time for yourself, if you have a lot of things to sort out. As a professor, I know the commitment you need to give to school- studying, clinicals, etc. there are only a certain # of excused absences you may be allotted, as well as a certain number of to,ex you may be able to repeat a course (even with a medically excused leave). You need to make sure all of your ducks are in a row. As a single parent, you need this career now ,ore than ever before. I understand that you want to get it done sooner rather than later. But you also want to do it right.
As for him: so,e guys just can't handle having a successful wife. Not all...just some.
