Although Graham's writing pulled me in emotionally, I didn't like this book much b/c heroine was TSTL(too stupid to live). She was a very passive person. She let others especially Hero & their son run roughshod over her. It was as much her fault as Hero's that he didn't see much value about her other than his convenient mistress of 2 years. She dropped everything in her life (friends, work, hobbies) during those 2 years & followed his dictates. She didn't change much 5 years later either. She still allowed Hero to control her & the only change were her mild but easily changed protests. Hero was a domineering jerk who uses & manipulates people for his own ends. I'm not convinced that he truly loved heroine for herself. I think that he loved her for loving him as no one else had & that's what he missed when she left. Basically both main characters are emotionally underdeveloped people who will likely continue their unequal r/s because it suits both their issues.
Warning: dysfunctional r/s.
