I mean it’s not great but it’s not bad either. Let me explain both.
It’s not bad, because she most likely just needs time to figure out what she wants. Her past heartbreak is probably still heavy in her heart and she probably just wants to make sure that being in a relationship is the right thing for her right now.
It’s not great because asking for space before your dating, will make you over think everything. And if you’re not at least keeping contact with that person during this break, the reality that their feelings for you might disappear is always there.
I don’t think you should feel any type of way, nor should you stress it or over think things though. All you can do is respect her decision, be a gentleman and give her the time and space she as requested. Hope for the best, don’t be pushy, or overly clingy and continue to be the person she liked in the first place. If it’s meant to be, it will all work out.
