What is the most romantic thing you have done for someone that has either backfired or was not received well by the person you did it for?

This one is going to be a doozy so strap yourselves in. TLDR at the bottom.

2nd year anniversary. I had decided I wanted to do something really special and different. She was around 18 or so at the time I believe and I was 20. I planned to go to the lake and have a picnic. The night before I go to academy sports and outdoors store and I have the great idea of buying a huge inflatable boat thing. I spent like 2 hours blowing into that boat since the air pump wasn't working properly. The whole time it's a surprise btw. I had told her I would take her out and to wear summer time clothes so the next day I show up at her place with a huge inflatable boat sticking out the back of an expedition and she's like wtf is going on. We arrive at our local lake and I place the boat in the water along with sandwiches and drinks. We sit down and and we drift off into the lake. So I'm unpacking the sandwiches and drinks, we're eating and having a good time. Before I realize it we're already halfway across the lake moving at what I considered a pretty high speed. She starts panicking when she realizes we have no control of the boat and are headed straight into a corner of the lake with nothing but tall ugly cattails. So there I am heading to a secluded empty part of the lake while my girlfriend is screaming and crying at the top of her lungs, cursing me out all the way I could see onlookers from across the lake just staring wondering what's going on. I'm trying to take control of the situation with some small paddles the boat came with but for as hard as I tried I could feel the water working against me and I so I stopped instead to conserve energy. The whole time I'm trying to think of a resolution to this situation but her incessant wailing made it so hard to think. But when I say she was crying I mean like it was BAD. Full blown tears streaming down her cheeks all the while yelling like a child. I finally just lose patience after about what felt like forever and for the first time in our relationship I full on yell back at her, "STFU I'M TRYING TO FUCKING THINK FOR A SECOND!" At this point she's whimpering since I had never ever raised my voice at her before this. I start grabbing the cattails and start pulling them but they're slippery and wet so and it strained my palms the same way rope kinda does when you play tug of war and it burns. I did that for about 7 minutes and she's still just crying. I finally get into a good position and realize that I had enough control of the water and the reason why it was so hard before was because the inflatable was moving in a set direction before with the wind and water. Idk how water works I just assume it was that. Now we were stationary almost and we werent totally surrounded by cattails either. I got the paddles out once again and I swear to God somehow got inhumanly strong and I just started rowing and rowing. I even commanded her in her distress to help me and there she is at the end of the inflatable flailing about with her arms in the water. Before long we were in the clear and drifting back to safety. Once we finally got back I set up a towel for and the little sandwiches and drinks I had for her. She was just saying how she wasn't feeling good and wanted to leave. Problem was the truck was across the lake so here I go on my trek which btw I had taken off my shoes because I didn't want to puncture the boat. Walking in the dirt road in the sun sweating my man parts off for about 12 min before I hitchhiked and got a speedy ride back to the boat drop off/in area. When I got back I packed everything in the truck. She gets in the passenger and right as we're getting ready to leave she opens her door and vomits. I didn't know this but appearantly she hates that feeling too and so now she's crying again. I hand her some water and after she's done composing herself I surprised her with my wildcard. I tell her to open up the glovebox and she pulls out, you guessed it a ring. Now it wasn't THE ring, but it was a promise ring. I told her then and there that no matter what circumstance came between us I would always be there for her.

Fast forward a year later and I ended up splitting up with her after my bestfriend revealed to me a weird Instagram post she had been tagged on with some random guy but it was really intimate and I remember the caption having like hearts and a cheesy quote or something. I confronted her about it and she seemed bewildered and tried to play it off but I saw through her bs and called her out on it. No happily ever after.

TLDR: I took my girlfriend on a surprise trip on our 2 year anniversary to the lake. Lost control of inflatable boat. Girlfriend panicked and cried and vomited. Burned my hands. Eventually got back go safety. Burned my feet. I pulled out promise ring after what she considered a horrible day. Fast forward a year later we're not together anymore.
