I keep receiving the impression that you and she don't really communicate, and maybe never have. I seem's that you're willing to outwardly appear to accept whatever indiscretions she does, but then internalize the situation without calling her out and discussing matters with her.
Did she actually ask to be forgiven or did you quickly forgive her so as not to need to discuss and deal with the problem?
Marriage involves a sacred trust which is freely given to each other when you married. She doesn't seem to understand that. She broke that trust long before she went to the hotel, first in reporting your private marriage matters to her parents, and then in sexting with another man. The actual sex with another man, was the ultimate trust breaking act. Although you don't want to hold the incident over her head, she should need to earn your trust again.She has severe OCD
And yet, her family and you, continue enabling this condition instead of helping her to obtain the help and support she requires. She needs professional help if she, or you, have any hope she will cope with the OCD so it is not always controlling her.
In support of fredo's prior comments, you also would benefit from counselling. Things will not change unless you're willing to allow change.
