Why do I have bad luck with friends ?

i meet lot of people but I don't know why the friendship does not last!!

I met a friend at college about few months ago. She was all nice and she made me believe that she will always be a good friend. She was open with me about her bad passed and we shared nice moments together and helped each other with school projects until few weeks ago she became distanced n not respondin to my call.

I asked her what's wrong she said she was busy I said fine. But she did it 3 times, she does not answer then I got a bit offended and said to her thanks for ignorin my call cuz it's not the first time she's doing it. She said she was busy agin, anyway we planned to meet each other but she gave me excuse that she'd have to go somewhere, basically she wanted to distance herself.

Today at college she ignored me! I did the same thing and ignored her. It felt really weird! I found out later she even blocked me!! Wow all this hate why? I have not done anything bad to her at all! We were friends and I wasn't the type who call daily cuz I understand ppl have life and I have my own life and we both have kids, but to distance herself with no reason I don't get it!? I am not going to try hard.

Btw this happens to me everytime I get close to someone especially girls!

I am sociable and kind, I am good looking and elegant. I like to talk about everything, so am not a boring person.

Sometimes I think maybe I was too nice? Maybe I asked her to help me with work? But then I also did nice things to her!
