How to overcome this jealous feeling?

I'm pretty sure that I'm jealous.. Or just afraid to lose someone I'm super in love with.
I love this girl and she use to show it.. She still does but its like were growing further apart..
I don't want her to feel that she needs to be with me 24/7 because thats not it at all!
I just don't like how she may say all this stuff about other people, like how this guy was like talking about her giving him a hand j.o.b or blow j.o.b.. Like she don't know it hurts me and I can't just say "STOP TALKING ABOUT THAT" because then she'll think I'm jealous, even though I may just be.. I just want her to know, I don't want to lose her.. She tells me how happy she is to be friends again, because we got in a fight over the whole summer, and it just seems like she don't are if were not friends anymore.
I start to wonder if she means it when she says I love you.. could she just be saying that so we can still be friends and not make me feel bad? What should I do?!

It sounds like there are some unresolved feelings between you too, but if you really want an answer to any of it, you'll have to sit down and talk to her.
With the things she says, you can maybe mention you rather not hear those kinds of things, and well if she thinks your jealous, than maybe that can be the conversation starter?

ok wotya gutta do to this guy is who was talkin bout her givin him hand j.o.bs and blow j.o.b.s, is to talk to him and tell you how you feel about her (if he isnt a close friend then just simply punch him in the face and tell him to back off)...ok when thats done you gutta sit down and chat with her and tell her how you feel about her...then do woteva it is you wer doin before and hope for the best
