What does my ex making no eye contact mean?

So we go to the same college and agreed to be on good terms even though she dumped me for an immature reason before even asking me about it. So I was pretty sore at her for doing that. Went no contact for a week, she gets a new Boyfriend and says she knows he will be able to commit to her because he just got out of a 2 year relationship. She says she didn't think I would commit because I wasn't calling her all of the time, even though she never even called me once. Anyways so even after she is immature about the whole thing, I care a lot about her, so I decide to be on good terms. Went on break a week later for a month. Had no contact at all the whole break. I come back and see her o the first day of classes. Me and a mutual friend of ours walk up to her and begin to talk, she doesn't look at me once and only talks to him even when I try to get involved in the convo. I see her again after that from a distance, we make slight eye contact and she looks away and waves. I see her again after that with a couple of friends and she attempts to avoid eye contact but since she had to directly talk to me for something she looked in my eyes then would look away and be all weird about it. Then we met ran into each other one time while both of us were alone. She tried to avoid eye contact then too the same way. Then today me and another mutual friend sat with her in the cafe and she made quite a bit of eye contact but then after a few minutes she noticed and tried to keep looking away. And then she pulled out a magazine to try and not have to look up. I want to e friends with her still because I understand why she dumped me and can admit defeat, but she is being awkward. I also saw something that I saw in her eyes when we first started showing interest in each other. When she broke up with me I did not see it, so I don't know what to think about the eye contact thing. Any girls know what this is about? Any help would be greatly appreciated. Thanks a lot :).
