What was your biggest 'dick move' towards a girl you were interested in?

one halloween a couple years ago,...i made plans to go to a haunted house with my best friend (guy), and then a girl i was dating wanted me to spend halloween with here elsewhere,...well, i kinda changed my plans and was going to hang with her on halloween. HUGE mistake. my best friend went full ghost on me and pissy and wouldnt talk to me (in person, we didnt talk via text or anything, but we hungout all the time). Anyways, after a day i was finally able to get him to forgive me, however, it was only after i begged him consistently and re changed my plans to drop my plans with her and go to the haunted house with him again. and i had to agree to never ditch plans with him for a girl again. Bros before hoes? ya..thats the lesson here i guess. lol

Idk. She wouldn't talk to me after trying s freaking long. Lied straight to my face and betrayed my feelings cause she didn't want to hurt me or some shit like that. I asked her if she still wants me around but never replied back

I've never really been a dick to any girl I really liked, certainly not intentionally. I think the worst I've been to a girl I like was back in my later years in secondary school, I was not feeling good at the time; depressed as hell and really kinda pissed off at a lot of things so as much as I liked her I really just wanted to be left alone but she kept pushing for an answer even though I clearly didn't want to answer at that point. But then if I remember right I threw her a pretty nasty scowl and said something like "Look, stop. I don't want to talk to anyone right now so leave me alone." There's way worse things I could have said but I could tell she was hurt by my response but I felt really bad about it and apologised a day or two after and ran her through how I've been feeling and she thankfully understood it wasn't anything personal against her. I found out that actually brought us closer and we eventually dated for about a year or so - she was great but that's all in the past so meh.
