OP I said earlier you could seem negative and that's not attractive. Your example message was about a great one and I have come across draining people.
But
It could also be that she doesn't like texting much.
Or, if she makes the effort when she has something to say, she could just be self centred.
I had a situation with a friend a couple of years ago where we had become quite close because of circumstances (and had been friends for a few years before that) and we both faced difficult issues in our lives at the same time but different things. I made myself available to meet up with her and chat when she needed it. She would text me to ask how I am and if I want to meet up and then I would reply and she wouldn't respond. A week or so later I might ask how she is and she would either not respond again or tell me she's sorry she hasn't been in touch but she's had a tough time lately with no irony considering what I was going through and made the effort anyway.
Eventually I stopped messaging her as it was clear she wasn't interested in being a good friend to me at that time or maybe she couldnt be.
The reason this situation came to me was because this friend at that same time was always posting on Facebook and Instagram so I couldn't accept she was feeling too down to text me. Yes it's up to her what she does and it's up to me what I do and I decided I wouldn't waste my time on people who couldn't take time out for me. I muted her on social media as I found it irritating to see her constant posts when I know she couldn't be bothered to message me! You could try that.
I used to be someone who made the effort to text people and stay in touch. Some of us find ourselves in that position but I have stopped being the one to make the effort and you know what, I'm happier. My friends still text me and I text them, some it's every few weeks and some it's closer to daily, but the friendships feel balanced. Friendships change over time.
You can't change what she does, you can only control you, so make yourself less available to her if the friendship is a bit one sided.
