One and a half month ago I've decided to stop talking with a girl I've been interested from uni in for many months by then, started avoiding her, not greeting her, because I wanted to move on, as from my analysis it seemed like I've been living an illusion and she probably wasnt interested. Though she never said no and we've had great interactions, it seemed like there were mixed signals at times, and I grew tired of it, so I've decided to take a drastic step and completely cut off contact, or at least attempt to do so. 

After two weeks she actually sit down with me during a break, as I always put my head down and lie on a table, because I'm generally not in a mood for socializing and want to get rid of stimuli a bit. She asked me how are things going and that I looked sad lately, didn't really speak with others and haven't spoken with her. I then told her, compeltely honestly, that I don't know how to talk with people and that I grew tired of trying. We then had some small talk, but I wanted to end the conversation; luckily others came by then and I was able to put my head down and lie with my hands crossed.

A week ago I was really frustrated after checking what I got from an Electornics exam, as I've spent a lot of time studying for it and somehow I got not too many points (turns out I did a dumb fraction mistake, because I wrote down the wrong inverse, oh well), so after classes I burst out and didn't want to talk with anyone. As I was waiting to cross the road and looking to my left and right, I didn't notice that she was beside me. She said "hey, are you also going to [park name I always take a walk through from uni]?". 

Some context - when I've started talking with her a couple of months ago, she told she also goes back home by taking a walk through that park, so I've asked her twice, but she always had something else to do, though they weren't explicit rejections. Either way, how ironic, that what I've been waiting for before happened exactly then! I never saw her come back through that park before, presumably because it was too cold, and only recently did the days become warm enough for that. She clearly wanted company, which is why she sasked, since she knew I always come back from uni hrough that route. So, what did I do?

I wanted to uphold my resolve, so I've looked at her with a surprised exception, didn't say anything, and started wallking away quickly when the lights turned on, so that she wouldn't be able to catch up with me.

A couple of days later I didn't go to uni, and my good friend took notice of that. Out of curiosity, he came up to that girl and started some small tlak, and then mentioned how surprising it is that I haven't come yet (I'm usually very early at uni). She then said that I "escaped from her" recently, referring to that park incident.

Should I uphold my principles, or did that whole park ordeal have some substance? Do you think she's somewhat sad about that incident, and my overall avoidance of her? Obviously I haven't entirely moved on, though I was quite happy for those 1.5 months. I've had a  conversation with the aforementioned friend, and he said I sohuld continue talkiing with her, as there was merit in all that.
