Ok. I read this whole text conversation, and the bold lines really stood out to me. I know your intentions were to be friendly and there for her, but I have a feeling she read the part of "My weekends are pretty lonely too. I'd love to spend time with you." that as being too strong, as silly as that is. She knows you have feelings for her, and at this moment in time, she isn't in the mood to maybe complicate things by hanging out with you just yet. Again, I say I know your intentions aren't to make things complicated for her, but just to be her friend, yet it's all in the way you word things. Maybe try to give an even more "just friends" response by telling her "If ever you need a friend to hang with or chat with to keep your mind off things, I'm here. I'm good company and a good listener." I hope I didn't confuse you. Only trying to help you.
