worst

Kill and rape her mom in front of her? (Wait, not in that order of course)

I don't know what this is all about. "Could have done" could mean a lot of things.

Then you might want to change the Opening post to might have instead of could have. Otherwise you're going to not get the responses you were looking for.

Example: Killing someones mom raping her (not in that order of course)

Not believed her, and broke up with her right when she needed you the most... Biggest mistake ive ever made
Luckily were still friends (shock I know)

making her cry from interrogating her.... at that time i was so pissed that i broke the wooden stool from throwing it to the wall....

Leaving him/her hanging by being dishonest.

I may have stabbed my ex in the face with a soldering iron because she was using the wrong tone. Also I needed more cowbell.

Lol wut. Worse thing I COULD have done. wow. That's a lot of stuff if you ask that question.

I could've kept her in my basement for years and rape her, get her pregnant, and kill the babies.

the worst thing i could do was make her love me. it just made it that much worse when i ultimately ended it.

Making her loved me and break up with her after she loves me so bad ..

which i will never do ,
but "worst" thing that i can think atm ..

Could have done? Mind-break rape and brand her in the ass with my logo.

I like where this is going.

The worst thing I've done to an ex was freak him out a bit.

With my first boyfriend, I was also his first girlfriend - so we were experimenting with kissing, and I didn't see what the big deal was. At the time I was living with my grandfather, who is absolutely awesome, and one day him and I were sitting on the couch together watching TV. A commercial came on advertising this one perfume that apparently is going to make you guys have the best fucking sex ever, and there was a lot of zoomed in kissing.

I told my grandfather, "I don't know what the big deal is, people make kissing sound amazing, but really I haven't felt that way about it." and he goes "That's because he doesn't know what he's doing yet, if a guy can kiss correctly, he can get your pants off in 2 seconds." and I just shrug and didn't think much of it. Then my grandpa goes "Does he try to use a lot of tongue?" and I said "Yeah, it's gross." and he said "See, that's the problem - next time you kiss him, just tease him with the tongue, make him think you're going to stick it out, and then pull back. You tease, don't give out."

So I said okay, and the reason why I was so comfortable with this conversation was just due to how my grandfather is. He's the kind of guy that when he saw Chris's photo on my cell phone he said "Oh, he's a nice looking young man, are you guys fucking? I hope so, you'd be dumb if you were to pass that one up"

or the time he told me how to make a bowl for weed from ice. -- That's just my grandpa.

In any case, I go to my ex's house and we're sitting on the futon and I'm actually on his lap kissing him and I do what my grandpa suggested, and my ex seriously says "mmm... where'd you learn that from?" and I smiled, because I absolutely could not resist saying it, so I looked at him and said "my grandpa" and he just closed his eyes and started laughing (he had a good sense of humor) and said "should I be worried about something?" so I (sort of) explained the story to him, I didn't tell him the part where I told my grandpa his kissing sucked.

Well i was giveing her a piggy back ride she tells me to go faster i was happy to comply. So in the fun she sat up on my back and put her arms out so we fall. I tore open my hand but she sprained he ankle. So she now rides on my back for two miles to our freinds hous to get her some firts aid going.

Thats like something out of a sitcom(Good story though). The worst thing I could do...Leave her at the alter and elope with her mom.

Tell her I was in love with another girl. Of course, I dated her for a little while longer. Then I dumped her. I then dated the girl I was in love with.. got cheated on.. went back to her and we're back where we started. Yup. Love is fun. :/

i remember tearing her shirt while we were at a playground. people where around us. she was embarrased.
