First relationship and breakup

As per title. I just got broken up with yesterday because she said that she couldn’t commit to me. it was my first relationship, we met online from a game, talked alot, first time we met she came over, we touched and in 3 days of us meeting, we had sex.

then she brought up alot of my character flaws which I agree were true mainly me being fat and not going to the gym, me playing games the whole day - but I feel that this should have been brought up during the r/s, and I would have instantly worked on correcting all these.

we decided to go on a break instead, where we are still dating but we take more time off for ourselves.

and the way she phrased it was she won’t try, but she never knows what the future might bring - in the sense that she can’t guarantee she will be single and stuff.

I talked to my friend about this, and he said she has already let go of me, and she told me straight up ‘why are you trying so hard for someone who has let you go?” my friend said that she only said to take a break to appease me.

so now we’re broken up, I still have feelings for her, a little bit, I think. We decided to just be friends. I’m kinda confused on what to do. honestly our relationship progressed way too fast, we talked, for about 3 weeks? got together, dated for about 2 and broken up. so now I’m trying to reset our relationship back to when we first started off talking, to try again, ask her out on dates and stuff.

We’re going out again in about 2 weeks for a theme park event. but I’m not sure if I should even do it. I don’t have very many female friends or friends in general in my life. I am thinking I should just go with my guy friend instead.

we still follow each other on her socials, phone no., etc. I don’t want to cut her off completely, but it feels iffy? like right now I am thinking, oh I am going to hit the gym like mad, then go meet her and she will see that I’m more attractive now, and she will like me back and stuff. but I know that is not healthy, that means I am not moving on.

so the question now is just, should I let go of everything but at the very least, follow her socials and stuff - I deleted instagram but I still folllow her spam and stuff.

or kinda move on with the half assed plan of working on myself and see if she comes back.

tldr: first ever relationship, I got too comfortable, did not work on myself when I was supposed to, r/s moved too fast, broken up but decided to go on break and then back to a breakup. not sure if I should move on or try again.
