Input: Text: i wanna preface this by saying in am in fact a teen living at home with his/her parents. through out the week, i've been in the process of clearing out junk in our spare room and cleaning it up for some family that's staying with us soon (mom's side). i'm the only one doing it because my mother is currently undergoing chemo and my father is at work almost all day. while going through some boxes of paper determining it it's junk or not, i found a hand written note. it was tucked away in a box that was fairly out of sight, as if hidden. i noticed it was my mother's handwriting. this is where i fucked up. 

me, being the snoop i am, decided to read the note. it was kind of vague and written in spanish (second language but i understood it). basically i can tell this was written last winter when my mother was diagnosed with stage 3 cancer. i can tell it's written to my father. she's basically saying how whatever mistakes he made is in the past and not to say anything to not ruin out family's christmas. 

she says (this really fucking hurt to read) that she thinks my father probably wished her cancer was terminal because she feels like he's eating her from the inside (roughly translated). this is where i got nervous. she goes on to name a "her". my mother says how she feels "like an idiot texting her as if everything is alright and letting her in our house". 

doesn't that sound like he's cheating to you guys? i'm not sure what to think or who to talk to. i currently have the note hidden and i'm not sure if i should confront her about it. everyone knows my mother is a saint and she probably would help my dad hide an affair and contain all that emotional damage to keep our family together and see me happy. i don't know what to do. 

what if my suspicions are correct? my whole fucking family is destroyed. this could completely alter everything in all of our lives and it took 3 minutes to happen. if you guys have any suggestions please i just need someone to tell me what i should do. 

edit: so, i talked to her about it. it turns out that note was quite old and from her first cancer scare (she has 3 types if you can believe it) when i was about 5. the woman was a coworker who she was jealous of. i misinterpreted the note. i believe her. she assured me if he ever did cheat she would not stay for me. i believe her. we're fine now and boy am i relieved. thank you all for the help.
