So I (21M) have been friends with a (21F) whom I did not have any intentions of being romantically involved with at any point in this story. 

So, let's call her Jane, had been in a rough relationship for a few years prior to myself meeting her, upon meeting her we really hit it off, I was there to support her through her breakup and her moving back home, we spent a lot of time together and grew close (so I thought). 

Jane was very passionate about achieving her dream and I was more than happy to help out financially for her to achieve this (probably my first mistake right?) And promised I would help her to achieve this, I care about her after all, we spoke briefly and she referred to me as her best friend so yeah. 

In the previous week's I didn't really get any contact from her and we stopped hanging out, I get that sure you need your space, but when Jane didn't have any one else to hang out with, or wanted something bought for her, she'd suddenly be there to hang out again? No effort outside of that. I spoke to her about this in a calm way to try and explain how it made me feel but it continued on regardless. 

Just before Christmas she messaged me regarding some stuff she wanted so i ordered Jane around $600 of PC hardware that she wanted, we shopped for this together and hung out for an hour or so for this, however once it was ordered and shipping date confirmed, I heard nothing again for around 3 days, just completely ghosted me. 

So they were due to be delivered tomorrow and I cancelled them, I let Jane know that she wouldn't need to wait for the delivery and all of a sudden I was worth the time again for a message regarding me being in the wrong and to blame for her not speaking to me. 

Am I the asshole for feeling used and cancelling the parts? I care about her and said I'd help her out after all..
