She wants a break?

She said she wants a break to think things over.. She said that she wont **** around and that i shouldnt be thinkin that for 1 sec. After the2yrs she has really been tru to me, she been with me almost every day. Should I believer her .. or is she gonna leave me ? I don't want to keep trying to talk to her to push her away but it hurts so bad... She also says she has really strong feelings for me too... so its hard for her to say that she doesn't ever want to c me because that is not true. All i wanto to do is Call her or message her or somthing becouse its all my fault for this .. and she said she wont talkbout it she just wants a break to think things over.. WHAT TO DO ??? I love her so Much..!! Is it a bad idea to send her a lil love letter ?? becouse its only been 3 days since we havent talkd.
