Your boyfriend, Sam, was a red flag. He would be mean to you, too much protective and jealous over you and it leaded to arguments yet in the end he would end up guilty yet acted like he was still mad. The days after, you would always be the one to apologize and everything would come back to normal.
Sam was a bad boyfriend, he knew that, but he didn't know how to show you his love in other way than being too possessive, wanting you for himself. One time he would hug you, the other grip your hair, an other time kiss you and lock himself into a room.
One night, you came home with a gift, something he wanted for months already. You walked into the house but Sam seemed pissed off that you left the house without him. You just gave him his wrapped gift and he just threw it on the floor. He started to argue with you and in the end, you had enouph.
"We're over."
You said and just left the house, annoyed. Sam was left alone, his heart clenched, hurt, broke. He didn't want you to leave him. No. He didn't want that. He loved you but his pride was always messing with him.
Days, weeks later, you were not apologizing like always, you were ignoring him. Sam felt like a piece of trash, he had to do something... He couldn't loose you, you were his everything.
