AITA if I'm thinking about leaving a girl who likes me for being too busy?

So I've been talking with a girl for a while now. However at beginning when we met, she sent much of messages and wanted to call a lot.

Well now last 1-2 months, she's been "busy" for everyday and 24/7.

-> She messages me once a day sometimes twice, but mostly once. And we don't call at all anymore. But she doesn't give dry messages either.

She always says how she really wanna talk to me more and likes me etc.

However, I don't mean she's not busy and I don't mind it really, and for sure I am busy too. But she's been "busy" for very long time now and I'm not sure am I the AITA if I would leave her for being too "busy".
