My Woman Says She Needs More Space

I've been seeing a woman now for about six months. I've told her how i feel about her and i show her how i feel every chance i get.

Lately though she's told me, more or less, that she needs some space. I'm having a hard time doing this as i've become attached to her.

We would talk all day long regardless of work or whatever else was going on. if we couldn't talk, we'd text. Now i can barely get a response from her but she says it's not me.

I want to spend time with her the way we were but i don't want to push her away. What should i do? Am i worrying over something i shouldn't worry over?
