Not sure what I should do?

there's a really sweet girl at my work that i kinda like and i talk to her a lot. She knows i like her but she didn't wana say much about how she felt with me and told me it was beacuse it was not fair to her boyfriend. So she dosnt talk about him a lot or when she dose she's saying how she not happy but dosnt wana be alone and I knew she was getti g me a gift for Christmas so i got her somthing small but she spent a lot of money on me. Im kinda gettig mized signals from her. Should i try to talk with her again or should i wait?
