[spoilers] Harry and Ruth

[Silktie]

I agree, he has definitely matured a lot. On Juliet, it started out as lust but he admits to falling for her a bit in the diary. I do think that he felt very guilty about the affair, and that this informed his future romantic relationships. The fact that he hasn't had a serious relationship since the divorce is telling in that he seems to have decided not to pursue women he wasn't really in love with.
