After reading the comments and sitting on it for a while, I realized how messed up my actions were and decided to make things right before Friday's show.
First, I reached out to Bianca:
Me: Hey, so quick update on the concert
Bianca: okay whats up
Me: So basically that ticket I gave you was for somebody else
Bianca: WHAT
Me: yeah it was for my friend and we had it planned
Bianca: So then why did you ask me to go with you
Me: I wanted to go with you
Bianca: Why?
Me: cause we was vibing and I thought it was gonna be chill
Bianca: So let me get this straight, you ditched your friend for me?
Me: Well I told him I gave you the ticket
Bianca: Dude we just met 2-3 weeks ago lol
Bianca: so... I'm guessing you want the ticket back
Me: No, I was just gonna tell you I gave him my ticket
Bianca: You want me to go to a concert with a guy I don't know?
Me: he's not on that don't worry
Bianca: you're weird so you weren't gonna tell me
Me: What?
Bianca: That the tickets were for somebody else
Me: you're right I should've
Bianca: I'll go but NOT for you cause I want to see this artist
Me: Sounds Good
Me: We are still good right?
She left me on read. I stepped back and gave her Dylan’s contact info so they could coordinate.
Next, I hit up Dylan:
Me: I'm sorry man I realized I fucked up and how inconsiderate I have been
Dylan: yeah you were so you got the ticket back?
Me: kinda I am going to give you my ticket and you are gonna go in my place
Dylan: Why? I don't even know this girl bro, does she know?
Me: Yes she knows I told her all the details
Dylan: bro that's fucked but I'm glad you came to your senses
Dylan: don't worry I won't steal her lol
Me:whatever dude lol
I stayed home Friday night while Dylan and Bianca went to the show. After the concert, I checked in with Dylan:
Me: How was the concert
Dylan: Bro it was Fyee, music killed
Me: I'm glad. Did Bianca say anything?
Dylan: She was cool, we talked about the artist
Me: Did Bianca say anything about me?
Dylan: Well she asked me if you did that a lot. I just told her the truth, that you're selfish at times and have tunnel vision. That time you forgot your AirPods, and left.
Me: Fair enough
Dylan: don't worry bro she'll probably text you back
A few hours later, Bianca texted me:
Bianca: Good job for doing the right thing, but I'm not interested anymore. Also be a better friend to Dylan, he hyped you up all night.
Me: Understood, hope it was a great night for you
She liked my final message, and that was that.
Dylan and I are completely solid and still homies. I scared away Bianca tho, but I learned a lesson. Your friends are a reflection of you, and Dylan proved he is a real one.
