<human>: Relationship of about a month. Girlfriend and I recently got back together after about a month, but she has been acting odd lately.

For one, she has told me that she doesn't want to be physical because she is not feeling well. She isn't sick, but we have not kissed/cuddled for almost a week now. She's told me she still wants to spend time with me, she just doesn't want to be physcial.

Thats okay, I don't mind that she needs a break, I still love talking to her. We continue to talk in school and on the phone, and we have spent some time on the weekends previous to her asking for some space.

Well this morning two of my best friends which I have known for years told me she was talking about me behind my back, saying I was clingy, and supposedly asked another guy if he had feelings for her.

I am going to mention it to her and see what she says, but I don't know what to do after that. 

Should I be worried? Can I trust her? I have been loyal to her, and I have been giving her more space, because she has mentioned that i'm clingy in the past. Is she using "I don't want to be physical" because of me? 

Ask any questions if I missed anything, I don't want to break up with her because she is the first girl I have really had feelings for.

Can you provide a brief overview of the text?
