You guys tread lightly when it comes to Adriana's mother and what she knew and didn't know. She could have been completely in the dark about her husbands outside activities. It's a cultural thing.
Back in the mid 90's, I dated and was married to a girl for about 5 years. Her father was Mexican and her mother was Italian. She easily could have passed for Selma Hayek's twin sister. Both of her parents were legal citizens, but they were deeply ingrained in the latin culture. Around their house, the man went out and made the money, and the woman stayed home and raised the kids and kept the house clean. Their worlds didn't collide. How the father made money, who is friends were, and who his girlfriends were, was none of the mothers business, and he reminded her of that constantly. His world revolved around bravado and machismo, and the wife and kids were ruled with an iron fist and rarely protested.
She had two brothers that were close to my age, and both of them were a carbon copy of their dad. Short tempered bullies, both of them were constantly on the take to make an easy buck and they treated their girlfriends like hell. My wife's dad (at the time) had a couple of kids outside of his inner family with other women. I never heard his wife mention it a single time, although she clearly knew.
I actually think her family had a lot to do with our subsequent breakup and divorce, because I really couldn't stand to be around them for long. Her brothers didn't like me because I was a white guy in the midst of a mexican culture, and me and the two of them had a couple of fist fights here and there due to it, I kid you not. My wife liked me because I didn't treat her like dirt in the same way that her Dad and brothers treated women. Regardless of her loyalty, I finally grew tired of being in the middle of the whole mess and opted to move on down the road. There were other things involved as well, but that also factored into it. When I was growing up, my parents didn't treat each other like that, and I really didn't like watching it. That may have also been where a lot of the friction played in when I was interacting with them.
All that said, I have no doubt that Adriana's mother could have been completely in the dark about her husbands outside activities. I've witnessed how that kind of thing works firsthand. I suspect there may be some users of latin descent that come out of the woodwork and start slamming me for my comments here, but keep in mind, this was my experience and my observation during that time of my life. It doesn't necessarily apply to everyone and every family.
