Should I leave her?

This is already her second chance. She walked away the first time and begged for another chance. It's been a few weeks steady then I took her to the mall and bought her some clothes and gave her a couple of my least favorite bottles of wine from my house. Now, she is not responding to my messages but reading them. I feel like she's unreliable and not a person I can share my day with. Am I crazy?
