I totally agree there. Its not just about the sex, its her overall attitude towards him. Beeing tired from / busy with work is one thing. But not even looking up when he says he wants a "proper conversation" (which is universal code for "Its about something important") and only reacting once he openly questions their relationship? And dont forget about that one time in the hotel when he just sought for some affection, and she was stone-cold towards him and then even went "well, ok, you can do me, then you dont have to pester me again with that"? Lady, he didnt even look for sex her, just some form of affection and love. Even just a small kiss and a hug would have meant very much to him in that situation.
In chapter 19 she even realizes that she does him wrong / that her behaviour is wrong. But even then she doesnt seem to at least try to change that somehow. Yes, she tried to invite him to dinner directly after that, but because he refused once, its all back to the start and nothing changed since then. Sorry but if you truly regret your behaviour untill that point, there is no way you just try to make amends once and then forget about it once that doesnt work out.
