Input:  Ok so to start off , I have no idea how to make an AITA post. It's 1:00 Am , and I'm sick at home. (This takes place in 2015.) Context: We were both very shy and only communicated with notes for the beginning of our relationship.

Anyway , my ex girlfriend ,whose name I won't reveal,  and I were together for about a year. Everything was great , until the end of the year. She didn't talk to me as much as normal.  She didn't even communicate with me through notes , she sat directly next to me but ignored any of my attempts to talk to her. Confused ,  I tried to ask her friends about it but quickly stopped , remembering that our relationship was supposed to be a secret.  Then  the year ends , I come back not knowing what to expect. We don't sit by each other anymore , and she doesn't sit close enough for me to pass notes to her either. I was too embaressed to ask her , if we were still together she might have thought that I forgot, but I was also scared , that if I asked she might say that we weren't.  I NEEDED to know. So I asked one of her friends if she was dating anyone , and her friend replied no. Even though our relationship was "Secret" I assumed the worst. The weirdest part by far was that throughout the following years , (including this one) , she was very polite , friendly , and overall more talkative towards me. She got involved in my friend group , hung out around me more.  She flirts with me often as well , and I had / have no idea how to deal with this. So what did I start doing? I started ignoring her. I intentionally avoid and ignore her and her friend group. (Despite some of her friends / relatives being my close friends.) Am I the asshole for avoiding her?
