Crushing so hard

What did i do to you

So I always wonder what did to you?? Did I say something did I hurt you what did I do?? And he still wouldn't talk to me so I asked someone and they told me I told his gf he was cheating on her with some girl. So I want to his face and this went down.. "What did I do to you" I said
" You said I cheated on my girl get out my face" Christopher replied.
"I wouldnt say nothing like that"
"But I trusted you and you goin say something like that to her you are her Bestfriend" Christopher said piss off
"Sorry hun but she not my bestfriend, I don't even talk to her but okay you can keep saying what you say imma go and leave y'all alone" I said confident. So as I started away he came behind me n said "she left me its all ur fault hun" but he know he didn't care bc he can pull any and every girl he wanted so he hop in my DMS and said this

And I started to think should I said bye because he said bye baby so are we going together now I feel like his girl goin say something to me. Idk what goin happened she goin say I steal her man or I wanted then to break up so I can have him. Should I text him back?? Idk what to do. I would never thought he would ask me that but he did n I said yes another way but I got with my crush! Omg I go with my crush!!?!?! 3 DAYS LATER........

"So u go with my man"his ex said
"Ur ex yea" I said goofy
"Im not playing leave or we will fight" his ex said seriously
"bet"I said . I reach my fist all the way back and bust her in her face then we start throwing real heads and he broke it up so after that me and him text is this what it said
