Is OTHER wrong in the post ? POST : So about 2 years ago, when I was a junior in high school, I dated someone who I considered one of my best freinds. We had known each other for almost 5 years before that and we both grew mutually closer, to the point where we actually able to plan half of our classes together for both semesters. She asked me out and we dated for a solid 3 months. During the time where we lived had a record breaking winter in every possible sense of the word so we didn't get to spend as much time together as we would have liked. I still ended up at the least being able to drop of her Christmas present to her home. However around February, with still a solid foot of snow on the ground, she sends me a text saying that she thinks we should separate because things aren't working out. I try and play my case and try to give her ways that I would try and improve. More phone calls making more plans when the snow finally thawed ect. But after a back and forth she finally revealed to me that she was already making plans to try and date one of my other friends. I had known this friend since 1sr grade and we have actually been drifting slowly apart in recent years but we still have that life long bond that will always be there. Since that day I have not talked to her despite her attempts of trying to say "let it go it's in the past let's just revert to how we used to be" and I could not stand that kind of logic. Honestly I was heart broken and the worst part is I just feel like I was blind to everything she was doing. Shortly before we had gotten together she was going through troubles with her anxiety and then current boyfriend. She had used me for emotional support then. I'll admit I was probably an asshole for being willing to be a rebound for her after she broke up with her previous boyfriend before me.but I can't help but feel she had just been using me so she doesn't have to deal with her problems. 

Tl;dr am I the asshole for being a rebound boyfriend that then refused to talk to her after being broken up with via text.
