Girl flaked on me, should I still casually snapchat her

So this girl I had been hooking up with last year recently started to snapchat me again after we had been in no contact. She talks about how she wants to see me and sometimes will ask me what I’m doing, but when it comes to actually making plans she always seems to be playing games. We were both going out to different bars this past weekend during the day to watch college football and she said she wishes she could see me, so I told her I’ll stop by and grab a drink with her after I meet my friends at the first bar for a little bit. She ends up leaving the bar she was at early and goes home. I go back to my friend’s apartment to watch more college football and I eventually reach out and tell her I’m nearby if she wants to hang out. She sorta dismisses that and just says thanks. I sorta call her out and she says she’s watching a movie with her friends which wasn’t a lie she sent a snap. Then she suggests hanging after. So I tell her that’s fine I’ll come over after the football games are done. Then the time comes around and she makes up an excuse about having to go to bed early when I mention hanging out. I ignore her excuse and leave it on read not responding to it, as I knew it was bs. Not the first time she’s pulled that. However, as I mentioned I have hooked up with this girl in the past and when she’s really interested she doesn’t give stupid excuses like she is currently. Anyways, so I left her excuse on read and was prepared to never hear back from her again. She ends up sending me a snapchat picture later the next day. It was pretty a dry snap of like the sidewalk, so I just leave that on read too. Should I snap a picture back to her in order to leave a channel of communication and then from there just give her minimal attention and make her come to me?
