Most Helpful Girl
I think she's being a little bit selfish. I mean, not wanting to be in a relationship because she doesn't have the time/she feels pressured to do other things is understandable. But telling you she wants to try again in the future is selfish. She's putting you on the back burner just so that she has a backup when the time is right. I don't think it's fair for her to say something like that, because it kind of makes it seem like she doesn't want you to even think about moving on, even though you're not together anymore. She doesn't have that kind of right.
In my opinion, you should be able to do whatever you want to do now. Just know that there's actually no guarantee that you'll ever get back together. She might change her mind somewhere down the road, which inevitably would mean that you've wasted your time waiting on her for nothing. If waiting is too painful, simply move on.
