The page turning effect can be for the long term, but it is much more important for it to be short term.
The reader should always be wondering "what happens next", and this is much of what causes page-turning. Your character, even by your own short description, can be facing a slew of multiple suspenseful decisions and choices that get resolved, but other suspenseful things face her. You can create a chain of them, and devise them in such a way that they overlap and show her character, so the reader feels more and more like they know her, care about her, and want to see what happens to her next.
she gets divorced ...
That is a big decision with lots of good points of short-term conflict and character building. What conflicts with her spouse led her to this decision? What is the straw that broke the camel's back? Did she agonize over this? Did she decide in a moment of outrage? Did she drive the divorce out of love or an affair? Did she get financially screwed in this divorce, or end up financially well off?
and learns more about love and sex ...
Another strong source of temporary conflicts; in fact nearly every Romantic Comedy is focused on just the first, 'love', with sexual compatibility a secondary plot.
How long before she decided to date? Did she take the initiative or did some guy ask her out? Did she agree right away? What went into making the decision to accept even a date? Sooner or later she gets naked with somebody, what went into that decision? Was it deliberate? Was it accidental? Either way, did she regret it? How many partners did she have in this journey? How did they disappoint her? What revelations did she find along the way? Was her heart broken by choosing liars, or promiscuous dates? Did anybody try to force themselves on her? Were they successful, or did she defend herself? Did she do anything new (that she had not done in her marriage)? Did she pursue anybody that rejected her? Did anybody propose to her?
... and finally sets out to find her inner self.
Why? Surely some sort of internal conflict brought her to embark on this course of action; what was it? If this is the "finally" of your story, whatever it was should be foreshadowed throughout the divorce and her various adventures in love and sex, something must be missing and that should make her marriage, her single life, her love and sexual activity all lacking something, and the point of the book is showing us how she finally came to realize what this lack is; and that is what drives her into this search for who she really is and what she really wants from life, love, and sex, what she in retrospect realizes was missing from her life-up-to-now.
By foreshadow, I mean do not say this explicitly; it should be something that looking back the reader can realize truly was missing, all the time, but must be behind the scenes as it were. You can pick whatever that missing element is (sexual, spiritual, intellectual, emotional), but you don't want to blurt it out and give away the ending.
Instead, figure out the consequences of this missing piece, and show us, again and again, those consequences, but not the cause. If you can't come up with enough consequences, you don't have a good story driver, think of something else!
If you can think of enough consequences, you engineer your scenes to show them, but like your readers, your girl does not realize what the common thread is in all her relationships. Until the finale. Then all those short-term suspenseful scenes, already resolved, can be seen in a new light, the conflict was all manifestations of the same thing, and she doesn't like this about herself, and now she needs to figure out how to fix herself and break this trait and become a different person that can be happy.
Give her a flaw, not one so bad we won't love her, and nothing you ever say explicitly or she ever realizes explicitly, but a general flaw you can show manifest itself in various ways for many scenes, perhaps with escalating bad consequences. Then you have a story, and the ending, even if not filled with action, can still be momentous: She finally realizes what she really wants to change about herself, and believably, with conviction, takes some momentous, courageous and irrevocable step onto the path of doing that.
We love her for that. The End.
