Is it worth asking for a 2nd chance after getting rightfully dumped or pointless?

My boyfriend of 7 months broke up after finding out I was originally dating him for a dare and faking things for the first 2-3 months. It was a recording I forgot to erase, where I'm making fun of everything, his phrases and used the word idiot a couple times.

Though I did eventually canceled the dare and didn't collect the money but he doesn't believe my feelings are real base on what he found. I let him walk out without asking for another chance. I only apologized once and said nothing much. Then the following day or so, I get a message from him. This was the message:

¨For someone that claims to love me, you didn't even try to stop me from leaving. If it was me I would've try winning you back but you didn't even try. It doesn't sound like you love me enough''.

Ironically I've asked another forum about wanting a 2nd chance but I yet I couldn't do it when the opportunity presented. If I had pleaded enough and rebuttal, there was a chance I would've got him back but I've never begged anyone in my life. That's really out of my character. I said awful things on the past recording and he found it. What's there to say? Is there a point in asking for another chance if they break up or really pointless? Did I do right in letting him leave without trying to win him back?

I've never in my life been the one to beg for another chance, ever. It feels similar to getting rightfully fired from your job because you did something wrong and then having to beg for another chance, pretty humiliating.

I'm 24 by the way, not 14. The system won't let me fix it.
