Some years ago, my quirky, nerdy but nice cousin had a much younger girlfriend whom he had just moved in with, and she had a baby from a previous relationship. He seemed really proud and our whole family was thrilled on his behalf, this was his first girlfriend, although he was in his late 30's. After a while he contacted me (I was 16 at the time), they needed a babysitter and since I had no school nor work at the time, I agreed. Things went well and I'd babysit her every day, and on occasion when they went out on dates. The dates stopped pretty fast into the relationship and I was now just babysitting during the week days. Eventually my cousin would sometimes just stay at home. He'd sit and talk with me for a while but would eventually retreat to his computer in the room next to where I'd be, while I was watching the baby. I found it odd I'd have to babysit when he was home, but it looked like he was working. Some days he would open the door wearing nothing but his briefs, but he had just woken up, so I chose to ignore it. The days went by, and I'd leave as soon as his girlfriend returned from work. I noticed they didn't really talk when she'd get home, I just assumed they were both tired after a long day. One day their dishwasher broke down while running and none of them were home. I had no phone at the time, and had to use his laptop to try to send a textmessage to my mom for advice. As soon as I opened the browser, his bookmarks were open at the side and a long list of really odd porn sites were there. I quickly closed the laptop, not really having the time to react while the water was flooding from the dishwasher, and hurried to his desktop. Again, the bookmarks were already open and a lot of search results such as 'babysitter', 'teenage girls brushing each other's hair', very specific search results (things that seemed extra weird to a 16 year old girl). Then I got bold and checked the time and date of the most recent results and most of them were from either the same day or time as I was usually there , and the last results being the same morning as I got there. I didn't dare typing in anything in case he noticed I had used his computer, so I just let the dishwasher flood. Things started getting weirder and weirder, they didn't speak at all and his girlfriend would tell me things about him when she'd return from work, looking very disappointed and annoyed. It was obvious she was holding back on some things, I was his younger cousin after all. But she told me they were going to break up and move apart, and that she had a relationship with her boss. I was shocked in many ways because my cousin had told me nothing about this, he was seemingly okay. At this point I really wanted to quit, but I didn't want to miss out on the money, so I was determined to just keep to myself the times he'd stay at home. One day I was there alone while the baby was crawling around in the livingroom, while I was making food in the kitchen. I suddenly heard this rustling sound, so I ran out to check what she was doing. She had dragged a plastic bag from behind the gap behind the couch. I placed her somewhere else, and while I was putting the bag away again I noticed something inside of it, a dildo . At first I giggled, I couldn't believe it, I checked what more was in there and there were several similar things, I felt so embarrassed and quickly hid it. Then I realised the baby had broken a box that one of the things were in, paper bits were spread on the floor and I kind of panicked, I didn't want to bring this up to either of them when they'd get home, but didn't want to pretend like nothing had happened. Hours went by, and my cousin came home. I decided I'd tell him, but told him exactly what had happened and that I was sorry and that although it was probably uncomfortable, I found it more funny than anything else. Halfway through my sentence I noticed he was really unaware of the entirety of the bag and especially its contents. He went from curious, to shocked to angry and I had no idea how to respond. Stupid as I was, I brought up what she had previously told me, asking if this could be regarding them breaking up. Once again, he looked like he was about to burst and his lower lip was shaking at this point while he was sitting down. He looked like a child. I was even more nervous at this point, because his girlfriend would return from work soon and I really didn't want to get more mixed up in this than I already was. He started telling me things, about his suspicions of her cheating, how rotten she had been, that she often threatened about leaving him, but not that she had decided yet, and especially not that she had told me. I went home as soon as I found the moment to, and I continued babysitting a couple of weeks until I quit. I also realised that his now ex-girlfriend most likely told me what she did in hope that I would (which I did) tell him ''for'' her, to spite him.

I know this isn't super duper exciting, but this will remain one of the most absurd periods of my life and forever changed my relationship with my cousin, and his parents and siblings' over the top appraisal of him. He still remains a loser.

Tl;dr: Discovered my cousin whom I once looked up to was a pervert, and his girlfriend was cheating on him.
