<human>: I'll try and keep all of the fluff out of it. My ex and I ended on an average note. We had the ups and downs here and there. She left me basically for another guy, and i'm pretty sure she's single now. We were cool (as in cool to talk to one another) but talked sparsely. I believe we talked a bit during spring break, she stopped responding so I stopped talking to her after that.

She texted me about four weeks ago saying "Hey, it's been a while. How've you been?" My heart dropped and I felt pretty crappy for a few days.
I promptly deleted the text as advice from my friend, and tried to move on. I thought it'd be better for me if I just didn't talk to her. However, it still lies in my mind here and there despite all that i've been trying to do. I've been busy, took up new positions, raised my grades, and even got better at my hobbies.
But it still just doesn't help. Sorry. I just wanted to vent out everything here. Thanks for the read.

Can you give me the gist of the text in a nutshell?
<bot>: Broke up with my ex a year ago, she texted me almost a month ago, my heart dropped. Don't know why it still has a strong effect.
