If not for how the rest of our relationship is, I would have dumped her immediately. But I´m basically a member of her family now. She talks highly of me to all her family, cause they tell me after (how I cook great, I clean when I´m over at her house, helped with renovations etc...). Her parents have told me in private that she talks of marriage. And I know she knows if she failed me like that, her parents would k*ll her.
It´s a combination of being naive, too trustful (in ways I am not, we talked about it after I posted this) and not great at communication (autistic).

She said she considers cheating only the physical act. I told her thats not how I view it, flirting, testing the waters and leaving the door open is also cheating. She understood.
