Search Results: get him back breakup

I was gonna post a picture of how I currently look but I’m a little emotionally sensitive right now because I just had a break up. So, girls supposedly get a new look when a breakup has occurred. I did just that. I shaved my head. I’m not bald but it’s barely a centimeter long. Kinda like Sinéad O’ Conner or Halsey I guess. I didn’t have long hair more like a bob haircut but when my boyfriend dumped me, I was obviously devastated and saw a picture of Halsey and on impulse grabbed the clippers on level 4 and shaved my head. I think I look more like me than ever but told I’ll never get a boyfriend now. I’ve bitched and moaned about being single for 4 years and I get in a relationship that lasted for a month and now I don’t want another relationship for another 4 years. So, I’m not worried about finding another boyfriend so soon. And I’m not gonna keep the shaved head, I do plan to grow it back out.
I personally like my new look.

Me and my man have many arguments
Even over small things
We have broken up several times
And im always the one packing my clothes when we fight
Him saying "im done, i dont want to see u again, i will not message/call"
Vice versa..
But 90% of the time he calls and tries to come back to me
And we get back together

Then yesterday morning we had a good time just going to a park and joking around
And having a laugh

Then we got home and we had an argument about a tv show
And then he got angry and just broke up with me
"Im done, you always argue every week, im done with your crap, i can't take this anymore"

And then we bickered back and forth
I started packing my clothes
Then he said
"F**k this. I dont deserve this. I dont love u anymore, I dont care about u anymore, go find someone else"

And then he dropped me home
He was still angry

Is this final?
How could he switch to not loving me and not caring about me in 1 second?
