Should I end our Relationship?

Hey everyone, I have many problem with my girlfriend for a while now that I don't know how to deal with it anymore. Alright first thing first.. We have been going out for only 3 weeks now. But the relationship to me doesn't feel like it. How?? She does not give me enough affection as I need. I live pretty far from her house. Like a good 2 hours away!! But I came visit her nearly everyday. Sometime I try to hold her hand but she push me away, even on someday I want to give her a kiss before going home..she continue to push me away! This type of stuff made me mad and so i question myself..does she not like me?? She treat me as if I'm her slave rather then her boyfriend. Always be telling me what to do..and then talk bad things about me. I guess my mistake is that I had try so hard to treated her like a princess. I really like her..but i dont want to be with a girl that treat me like shit. I dont want to go home everyday from her house feeling so shitty. This is my first girlfriend that I have. So I dont know what the trouble is..am I over-think? over-exaggerate?? I don't know..But should I keep this relationship?? Because some day she give me kisses that i need and affection that I wanted. But some other day it's nothing..AND SHE NEVER CALL ME AND EVEN WHEN SHE DO..SHE NEVER STAY THAT LONG TO CHAT. I try to call her and text her but none of that is working out. She havent complain about our relationship..it is just me. Because I'm so tired of pleasing her and try to make her happy. So what do I do??

Summarize: We never have late night conversation. Barely text each other. But we do talk and comfortable when we with each other.

She push me away too much when i want to give her affection

She's not a princess. She's a bitch. Chuck her.
