I think the best thing you can do is know things will turn out the way they're supposed to, and if they don't, then we have another life for situations to repeat themselves, so all you can do is try your best to take care of YOU, and if you start thinking of the person, maybe write a story about a date you imagine going on or something that makes you feel like you're together. Because if it's meant to be, you will be, one day. Hope this helps.
