<human>: So, this is probably going to sound incredibly lame but my girlfriend broke up with me about a month ago. It was pretty mutual so while I was really torn up about it, I am now back in the game, primarily using Tinder.

Now my ex girlfriend has a friend I'll call Elanor, who I am very interested in. While swiping through Tinder yesterday, I found her profile and naturally I swiped right. I didn't really expect anything as she probably heard all sorts of "lovely" things from my ex girlfriend. However to my surprise we matched!

Later that day I sent her a message. It was just a simple "Hey what's going on." because we know each other to the point where we know each other enough and say hello to each other regularly whenever we see each other. Strangely enough I didn't get a response. 

I know she uses Tinder and such regularly and I feel like she swiped right on purpose but I'm not sure how to continue. Should I message her again? Or should I just forget the whole thing and unmatch her? I feel like if she wasn't interested she'd just unmatch me but she has yet to do so. I saw her again today and she acted totally normal but I'm pretty sure she saw my message. Basically, what would you do in this situation, Reddit?

Can you summarize the given text in a few sentences?
<bot>: Match with ex's friend on Tinder, she doesn't reply. Still hasn't unmatched me so I assume she's interested. What do?
