Does my ex remember the day she left?

So, today i think was the day me and my ex broke up last year. She left because we met less, and our thing got one-sided. Only becuase i was focusing on school. Yet, my ex kept it going for 4 months. She broke up once like a month before and them came back like 1 day later becuase she said she loves me, but the second time she didn't. So, after she left, maybe 3 weeks later she was seeing someone. (at this point i used to talk to both my ex and her sister). So, as usual i got annoyed worried and started to be like "low" calling, texting a lot. Then in like May she blocked me, ( now, a girl (her friend) added me the day my ex broke up and didn't talk). So, my frined added her and she always like lied and said things "over" to make me jealous. So, then later her sister blocked me and then few days after my ex added me. SO, not for teh next couple of months. we talked like once a week. (our talks mostly ended up teasing each other or like flirty) and we met 2 times, we called a few times, and she made good eye contact when we met, she didn't make any eye contact after the break up. So, my ex texted me and met, called behind her bfs back. Later he found out and i feel he forced her to block me again. Also, when we talked, she asked me 2 times, if i found anyone. and i can hear her, and see the tone of her voice, she's faking any things. SHe would be mean to be like, i dont care. then when she asked i found anyone, i asked her why do u care. she's like becuase things chnage and people can care. THen, i found out that the friend who added me when she left, was her close close friend (so was she spying?) then a few months later her sister added me randomly. HEr sister doesn't even like me. she added me for a week, didn't even say Hi, then a week later removed me (spying?). So, then now, does my ex still have some feelings? does she remember the day?
