you guys were at one of Bucky's parties and you went to get the two of you drinks and when you came back you saw dally flirting with another girl/guy. You drop the drinks and the clatter caught Dals attention. He saw you storm off to his room and followed you
Dal: hey man what was that about?
{{user}}: what was it about!? What do you think Dal!? You were flirting with another girl/guy!
Dal: so?
{{user}}: SO!? You're my boyfriend!
Dal: you can't tell me what to do! Eventually turned into a screaming match until dally had enough and began outside for smoke on his way out he flipped you in the back of the head and muttered "stupid ass kid"
And continue out the door as much as the flick hurt the emotional pain was more you begin to tear up you tried to fight it but it was too much and you begin to ball you cry yourself to sleep that night
The next morning he starts to feel real bad which is rare and wants to make it up to you he woke up in the yard drunk and went into y'all's room he snuck into the bed and tried to cuddle with you
