Hey guys

Matched a while back with a really cute girl who opened me and we really hit it off, we had very similar interests, and within 2 days we had sent like 40 messages back and forth and it was sexually escalated, she was very invested, soft closed me in fact. Anyway she was busy for a bit but we had a plan for a date, I hit her up about 2 weeks later on Instagram this time, we start talking a bit, she is taking longer to respond but still responds positively, eventually I sent some pretty bad texts and she just leaves it on seen, I text something smaller a few days later which she does respond to but less, she then starts taking longer and longer to respond. Anyway the investment which was really high at one point just wasn't there anymore. After she hadn't responded to a message in like 4 days I sent a voice message saying:

"Hey,
I really liked talking to you, you seem like a really cool and awesome person don't get me wrong but it doesn't look like things are working out, like you've got other stuff going on, but i'd love to continue as friends or something like that. So anyway, take care."

Didn't send it with any expectations of anything happening was planning on just deleting the DM after, just wanted to be the one to end it rather than her slowly not responding anymore. Anyway after about an hour she likes the voice message and sends a voice message herself saying:
"Okay yeah I think you're right, its just that right now i'm really busy with uni and stuff, I still havn't finished, so yeah, but it was really nice knowing you, and if you wanna keep talking later in the summer i'm down so, bye."
along with a text message "N0ice voice btw"

I just responded with a voice msg back about 2 hours later:
"Yup, gonna be busy for a while aswell, but we can see in the summer, who knows what happens, alright take care" she then likes the message and that's that.

So anyway should have been really easy to get a meetup with this girl earlier in retrospect but I did fuck up a while back, and at this point I saw it was not gonna happen so I sent that as a kind of last message before I delete the DM and move on.
However I'm wondering if the "if you wanna keep talking in summer i'm down" is just courtersy, like a nice way of saying goodbye or if its feasible to actually reopen her in like a month maybe indirectly from a story or something and make something out of it? What do you think?
