Background: Myself beta-like transforming to Alpha talking to an ex, who was driven away by the Beta-ness.

As of late, I've been acting completely different than prior. I'm no longer replying to texts as frequent or not replying at at depending on the context. She has solely become the chaser and I can tell it's getting to her.

She finally asks: Have you been mad at me as of late?

Honestly no, I haven't been or shown signs that I was. What would be a good reply/how should I handle this?
