What does it mean if she says she’s busy and apologised for it but she’s online a lot?

We are both bisexual.” her Snapchat score keeps going up and she’s been telling me every time I text for the past few days “thanks for understanding I’m so sorry I’m really busy with uni work ❤️ I will text you when I can please forgive me ❤️“ I feel like she’s taking the piss as she’s online watching my stories ect?
