<human>: While in the relationship and outside of it, i do things like going the gym, tennis, playing games, and hanging out with my circle of friends (she's in it too, we're a pretty close knit group, everyone's known each other since middle school). However, because our relationship was long distance since we ended up going to different colleges, we texted and skyped a lot whenever our schedules allowed for it and i kept doing everything i listed above. I had just recently finished one of my big projects and had planned a bunch of things to do for the rest of the summer when she returned. 

However, after a few days back, she dropped a bomb on me saying that she didn't think it could work out with the uncertainty of when she'll be able to come back to see me (if at all) because of her research/internships and wouldn't be able to manage seeing me for a bit only to be gone for maybe 6 months or more at a time. So while i understand and don't blame her for it, it still sucks and all the things i had planned to do with her in between hanging out with our group, tennis, gym, etc are gone and i'm left with huge time gaps with nothing to do. So if anyone has been in a similar situation, what did you guys do?

Give me the gist of the text in a nutshell
<bot>: i already hang out with my friends often, play games, go to the gym, and play tennis, i need help finding things to do in between them where i had previously planned spending with my gf
