Girls what does it mean, if a girl says she needs space but still talks to you but doesn't make plans anymore?

Okay so I just started seeing this girl a month ago and we would chill every weekend. She would always greet me with morning texts , with lots of emojis and call me sexy and whatever then it just stopped. Her texts started getting dry and she started falling back a bit. I do think I might of come on a bit strong the last time we hung out, so how can I fix this? She did tell me she needed space which I understand but why the change in tone with the texts and everything?
Should I still pursue her or cut my losses
