Is she trying to ruin this again?

I was with my 4 bffs. Then well if u have read my other questions then u would know him but yeh. He likes this girl and she likes him and it really makes me jealous. She tells him everything I and everyone else says to her. I try not to be mean to her otherwise she'll tell him then he'll get up me and we'll go back to me and him not talking and yeh. I asked her why she is doing this and she said idk. I also asked her why do u think I still have feelings for him? She said cause love never ends. I said after awhile it fades away. It depends on the person though. I also found out that she aksed 3 of my bffs to tell me that they were gonig out when they wernt so she could make me jealous. >:(
I just dont know what to do. Then my best friends when up to him and said that they were going to the movies and he was like :OOOO What? and he shook his head like I dont think we r.

If u dont know who he is then I have liked him for 4 years and I never told him. My bff acidently told him and that kind've ruined the whole relationship cause he doesnt like me that way and I get that. I just wanted to be friends. He was really nice to me for 1 year then this year he was really mean to me at the begining of the first semester at school. Then he said that he doesnt hate me its just I am to quiet. So ik I was stupid but I wanted to see how he reacted so I was loud and then he said she is too loud I liked her better when she was quiet. -_-
Idk how to talk to a guy lol so I just say hi and sup and then yeh the conversation goes by there. Thats the whole story.

Idk what to do. Whenever I get over him something pulls me back to him. Idk what. My friends said like 4 months ago when he started being mean to me just drop him and find someone better who treats u nicely not like a jerk. I tryed but that didnt work.

How can I fix this?? If I be mean to her she will tell him then we'll go back to not talking to eachother. We just started to talk to each other again I mean come on give me a break. I just dont want to go back to that again. How and what should I do?

I think you shouldn´t be friends with someone who tries to make you jealous by telling lies or who tells your other friends to lie to you. She seems to be some sort of frenemy, you should try to keep distance from.

And I really recommend trying to get over him, the past events with him make very little hope that a relationship with him will actually work. You will save yourself from a lot of pain, I'm sure.

If you have problems getting over him I recommend following:
Collect 3 or 4 reasons why you shouldn't/can't/don't want to be with him.
If you have the feeling of getting pulled back, some sort of weak moment, when your heart yearns for him, breath in while counting until 4, then do the same breathing out. Repeat this 5 or 6 times to calm down, and then think of your reasons. I hope this works to repel these pullbacks.

So I hope I have helped you at least a bit.
