"is it normal that my girlfriend is changing"

What was the fight about? Did you start the fight or did she? What did you say to her? What did she say to you?
All these things are important to know to even answer your question.
If you were a complete asshole and said messed up things to her then I can understand her distancing herself.

Like Nick said, she has a right to disregard your calls, your texts, or she could just turn her phone off. But when you try and take things by the reigns and "scold" her,sorry dude, that is not your place in life until you are husband and wife, as if it would ever happen. Just because you and her are "dating",, long distance I kind of assume from your post. There is a way to talk to females and there is a way that you don't ever,as a "man" talk to females in a way in which you are trying to dominate them emotionally. That's going to make them think and feel Like you are a control freak. If that's true, there is no way in hell she should be with someone like that. There is a saying " You get more flies with honey, than vinegar". So if you decipher that little phrase, it's saying treat them with kindness, be a gentleman, not a jackass. Eventually in time you will learn things that are vital to a man's survival. But for now think of it like this, how would you want someone to treat your sister, your mom if she was single, or your daughter, if you had one. You treat women with respect until they show you they don't deserve it.

she has a right to distance herself completely and it doent matter that you get pissed either. so what i think or what you think doesn't really matter. you can cry over spilled milk but in the end it still got spilled.

About what were you fighting with her, and for what reason or why was she "begging" you? What makes you think you have the right to scold her, who the fuck are you to be trying to "scold" her? You ain't her mama or her daddy so you ain't got no damn reason to be scolding her!

Maybe the reason she's different is because she's coming to her senses? Maybe she's much less available, because she doesn't feel like sitting on the telephone while some asshole control-freak "scolds" her. Maybe her folks know you're not good enough for their daughter so they've perhaps made some amends, put some old resentment's behind them and are working on strengthening their bonds which may be why she's helping her mom around the shop more. Maybe she met a much nicer guy who treats her with respect, and meets hers parents approval. Maybe she's already broken up with you in her head, and is moving on with her life? Regardless, good for her! So what if she's lying, maybe she just wants you're bossy ass to leave her alone now?

I don't think anyone on this site appreciates how nonchalantly you talk about "scolding" this girl, and the fact that you are completely oblivious as to WHY she doesn't seem to want to talk to you much anymore only makes it worse. Why would anyone want to be wasting their time in a long distance relationship with a control freak who scolds them like they're a child? I can't even remember the last time I scolded my Siamese cat!

I can tell you exactly why you're "falling for her more", it's because she's not very available to you anymore. Maybe you are a narcissistic person who abuses her verbally and emotionally? She probably wasn't very attractive to you when she was "begging" you which was probably why you didn't want to talk to her. Now she's not very available so you are becoming more and more desperate for her. Narcissists always want what they can't have, and lack respect for those who love and care for them, because they secretly have low self-esteem and thereby think if a person likes them then there must be something wrong with that person. If she starts paying attention to you again you may very well lose interest, and go back to treating her badly, because you probably have issues. Seriously, how can you not know why?
