"Proposed to my girlfriend today. She said no and called me cheap after looking at the ring. It cost £400," he wrote on the secret-sharing app.
"So I dumped her. Took it back and got an Xbox One instead."
Others revealed how their proposals were not only rejected, but their girlfriends took the opportunity to rub salt in the wound by admitting to infidelity.
"Proposed to my girlfriend last night. She said no and confessed she was cheating on me with her ex from high school," reveled one anonymous poster.
Another added. "Proposed to my girlfriend today, she said no. Apparently she's been cheating for the last four months."
Others shared their heartbreak after planning elaborate or public proposals only to be turned down.
"I proposed to my girlfriend of three years last weekend," one man explained.
"Candles, rose petals, the whole nine yards. I even got her a kitten with a ring tied around his neck. She said no."
Another admitted: "I got 100 people and all of our friends together for a flash mob proposal. She said no."
"I proposed last month,' another man confessed. 'She said no in front of my parents and siblings."
And it wasn't just men who have been rejected.
One woman said: "I proposed to my boyfriend today. He said no and that a 'woman shouldn't be the one to propose in a relationship.' I'm so hurt."
Meanwhile, some of the women on the receiving end of unwanted proposals did explain their reason for the rejection.
"My boyfriend of 2.5 years proposed last night, but I said no," explained one young woman.
"He's the love of my life and I don't ever wanna be with anyone else, but I'm 19 and in college. I'm just not ready."
Another said: "My boyfriend proposed to me today and I said no, everyone is making me seem like a bad person but I just don't want marriage anytime soon."
Another woman added: "My boyfriend proposed to me but I said no because of his daughter. I'm not sure if I'm good enough to be her stepmom."
One man explained: "I proposed to my girlfriend and she said no because I was in the military and she didn't want the burden. Why the hell were you dating me then?"
Another said: "Just proposed to my gf this morning ... She said, 'No, you can do a better proposal than that.'"
But while some women at least gave a reason why the answer was no, one didn't even respond.
"My boyfriend proposed to me over text... I never replied," one woman wrote.
