FRIENDSHIP OR NOT ?

 Real or Fake?

I have 2 'best friends' completely different character, looks, hobbies. I've known them for such a long period, but I've got to my senses that something's wrong.
What's funny that they don't really like each other, so I have to meet them separately. 

M. I've known her for almost 6 years. We used to be in the same school and we we're inseparable classmates. We did hang out a lot outside school, talk a lot on the phone and even going together to school because she lived 10 min away from me. The best part is that we never fought! We always understood each other.
Years passed, we graduated, went to high school. Of course new school, new teachers, new friends. Everything changed. We stopped seeing each other, texting/calling. She was busy, I was too.
But there we're times that I had a bad day and I needed someone to talk to, I did not have anyone except for her, so I called her. Even though what happened we're still friends, but it's not like before.
I should be the one to text/call her to meet up. We plan something it will end up differently and she'll be doing   it with her other 'friends'. I've never been to a party in club, she'd promised to take me but it didn't happen.
Yesterday I saw her best friend with 'someone' in Mcdonalds, I was sitting behind them. It turned out it was M. and she didn't even recognize me,when they we're leaving (she was just standing next to me). I sent her a text afterwards and this morning a got a text from that she wants to meet me.

V. we've met in kindergarten. We we're best friends forever,we did almost everything together. I don't quite remember how did we exactly met. After kindergarten we went our separate ways to elementary. Since then we didn't have contact with each other. For all these 6 years I've been hoping that one day I will meet her again. And it happened.
There was this website 'grono' (there was no facebook by then but it's almost the same as that and it was famous here in Poland) and I found a link of my kindergarten batch year '93. And there she was :)
I was so happy that I've finally found her, I didn't know what to do.. Was I supposed to write: hey what's up? or :hey wanna meet up ? I didn't know.. A day later I received a message from her that she would like to meet up and to talk about the old times way back in kindergarten.
So we met, ate a doughnut, talked a lot and laughing from what we did when we we're small. It was just so nice to see someone after few years.
We did see each other a lot , so we could get to know each other. But it seemed as if knew each other for a long time at the beginning. Later it was becoming worst. She always wanted to see me, was jealous that I had more nicer stuff, saying that I was like her 'sister' but we we're more like the opposite.
When she was with her friends, she was acting different, as if she was trying to someone else. V always wanted to be like her friends, to have clothes from the expensive stores ( I had to borrow her) always had to have new shoes, everything!
She'll meet me if she needs anything, or I just bought something new and needs to see it, that she has very important thing to say (which is not). And If  I need someone to comfort me she'll start talking about her problems, like screw me. -.-
 I gave/bought her a lot of things and never really heard a word like : thank you. Always lies to me,  Forcing my sister to smoke ( she was 13 yrs old that time), asking her if she would go party with her
And what kind of friend would do that?! WTH ?!
