Hey guys so I was wondering how to restart an old thing I had?

Some backstory. I met this girl last year and and we really hit it off. We hung out a lot, went out for drinks and food multiple times, and just had fabulous chemistry really. Unfortunately during this I also had a girlfriend (who was completely toxic and I am rid of now). Because of this I never really made a move, and I also made sure it was abundantly clear I had a gf at the time.

Anyways cue to earlier this year we were hanging out and the chemistry between us was crazy to the point where we almost hooked up (I had to cut it off because im not about that cheating life). So after that I started to distance myself for obvious reasons. We still kept in touch and would occasionally send snapchats to each other (non-sexual), but never really hung out or had serious conversation.

Well after breaking up with my ex recently, I started talking to the girl again. Thing is now she seems a lot more distant. Ive suggested that we hang out multiple times, and even made the proper plans too, but each time she just keeps flaking last minute. Like she would say "that sounds great!" And when I would text her the day of to confirm, I get some random excuse.

So i guess what im asking for is what do you guys think i should do? Just cut my loses and find someone else or actually try again with this girl, because we really could have had a great thing.
