OK,first off,dont take any of the things I'm gonna say here as an insult , they are not that , I'm just trying to help you see some things that I get the feeling you're not seeing.
You know , there's a very thin line between being alpha and being emotionally unavailable.
Most guys live under the impression that being alpha means ,among other stuff :
"I will never apologize no matter if I fucked up or not"
"I will never show any form of emotion towards any girl and then I will end up not knowing why she slowly backs away"
"I will show no weakness ,ever".
Weakness doesnt mean admiting you are / did wrong. It means not being able to do so !
Being alpha means being superior to others. Being dominant.
Being a little bitch and not knowing when to say "I'm sorry" or not knowing how to express your feelings (or not letting yourself HAVE feelings) is mainly lack of character. You can not be alpha(true alpha) without having character.
Anyway , I would say that 8/10 times when girls get buthurt over stupid things and ask you to apologize , they do it cuz they feel you're not giving them enough emotionally-wise - and yes , most times they're right -. The fact that they want you to apologize for something that looks stupid actually translates to: "I want to know if you care enough for me to try and make me feel better".

all the cute things she does for me stopped. she making more plans with her friends then me. and shes starting drama over little things.
Do you do cute things for her ?
Fact is , when people give they also want to recieve. Remember to always give back. Not doing so won't make you alpha , it will make you stupid.
Any of the things I said might be a reason as to why she stopped chasing you. Everyone stops , at some point , if the start feeling like nothing good will come out of that chase.
