Not sure how to explain it. I liked the idea, but the overall felt mediocre in the end. I felt like there was a lot of unnecessary sex in the middle--hot, but unnecessary. The middle felt very PWP, but it was better toward the end when there was more going on in their lives. Time passage was difficult to tell. POV switches weren't all that great in some cases. The typos really started annoying me as well because after a while they drag me out of the story. The end also felt very abrupt even though the story dragged at times (because the beginning and middle setups took a bit long), and thus I wouldn't have wanted the ending to go too much further. (Catch 22, I know.) 
 That said, I liked the characters. They each had their own personality and issues, and those were dealt with pretty well. They fit together, and their situations were handled well. Just not enough to overcome my other issues with the story.
