<human>: Can you condense the text into three sentences or less?

We've been dating almost 9 months now, and recently we've been having problems. She says I'm very blunt in how I speak and handle things (anything, not just specifically in our relationship) and it bothers her extensively. We've recently talked on the subject, and I've come to the conclusion that I need to change, not only to keep her happy, but to better myself. She, on the flip side, said she'll try to be more tolerant and patient with me until it basically clicks and I understand what it is exactly that I'm doing and how to fix it. 

Now, I get it, things can be frustrating when there isn't immediate change, but it hasn't even been a week since we talked and she's already getting frustrated with me and giving me the silent treatment. I'm trying to change, realize that I'm being blunt and become more soft-spoken, but realizing it is hard and will take some time.
<bot>: Girlfriend doesn't like how I speak, is still easily frustrated after we've talked about it and come to a consensus.
