Sorry for the wall of text.

So a bit of backstory. I was friends with this person for a few years, and at the start of this schoolyear we went to different schools. At the end of last schoolyear, I noticed that I was always the one iniating contact, whether that be just texting or asking to go do something. Now, they weren't ever hostile towards me or gave any indication that they didn't want to be friends, but they just didn't seem to have any interest in doing anything with me outside of school. I noticed this with all of my other friends there as well, so when I switched schools I just decided to stop contacting them. I stopped texting them, didn't ask them to do anything, etc. Just to see if anything happened. And nothing did. No one tried getting in touch. So I just decided, fuck it, if you dont want anything to do with me then I'll stop trying. Now my friend texted me out of the blue, for the first time in months. Im not sure what to do. AITA for cutting of contact?
