It is very much true, Italian. The OP does not want to face the consequence of her choices.
She has flatly contradicted herself as to answering questions. I will come straight out and say I do not believe her account. She has not addressed the contradictions I have posted.
The phrase 'I know you told lies and I feel he wants to jnvestigate each time I said I was done here (somewhere) but wasn't' can be read either way, I'll grant that, but at this point 7 years on, it should be clear to the OP, if she is referring to the lies she told at the time she was having the affair, that the H has a very sharp memory. Or that the time of the affair is very fresh in his mind even at this point. I am not sure why she does not understand that it is all still preying his mind and is wondering if something out of the ordinary has happened, or if the H has bumped into the OM. If she is referring to lies ('white lies') she may have told in the intervening years that her H has discovered, she needs to understand the impact of these.
In this regard, keeping her phone on silent even now is a really poor choice for someone who had an affair. It doesn't matter what her preference is as far as beeping goes, or how she doesn't want to be a slave to her contact list. This is putting her own preference ahead of her H's very clear need for reassurance.
The fact that she keeps on making throwaway comments about her own behaviour such as the one about the phone makes me suspect the OP really is not aware of how she is coming across to him. It also makes me wonder if the H recently spoke to her about the phone on silent and while it is on her mind, she hasn't understood why it would be an issue.
The script is well recognised, Italian, whether you want to believe it or not. It was very obvious to me as I read the OP's very predictable comments, minimisation, justification, and evasions.
I think Tolstoy was wrong, or at the least, his statement requires a clarification - it's possible that as a writer he found dysfunction more dramatic to observe and write about than happiness, and dysfunctional people more interesting than those who are poster children for the seven habits of successful people.
