<human>: Can you provide a brief overview of the text?

So i had feelings for this girl all through My A-levels but she had boyfriend all the way through and i didn't say anything because i didn't think i was that kind of guy (turns out i am but thats not really important). 

Anyways we both go to different universities but we still talk all the time and after being there two months she dumped her bf from home, which would have been awesome if i hadn't stupidly gone and got a gf in those two months. I break up with my girlfriend just before finishing my first year and coming home for a lot of reasons but mostly because she wasn't my best friend. When i got home i decided to ask her out which ended with her saying she loved me like a brother.

 That hurt a lot and I also had to deal with the fact that she was upset because she thought this was going to ruin our friendship and she's smart because it did. Instead of dealing with rejection i took one of my 'Lads' advice and became a party animal. Weed, excessive amounts of alcohol and random flings became my summer as i became what i once derided a 'Lad'. 

We stopped talking and mutual friends told me that she really didn't like the way i was going with my life and tbh it was far away from how i used to act. I used to love poetry and old literature and we really bonded over those two things especially our favourite book the great gatsby.

The main problem here is that she rang me up yesterday in tears wanting us to be friends and to hang out and it to be just like it was and she wanted me to go see a musical with her. I'm all down for that it's just she also said that she doesn't like the way i act nowadays and that she wants to help me be the kind and sensitive boy i used to be. 

The problem is I don't know if i want to change, i recognize that im being immature and destructive and part of be doesn't care. I don't know what to do. Who do i choose to be? can I be Both?
<bot>: My bestfriend rejected me and i changed from a nice guy to womanizing party boy and she wants me to change back.
