Hi girlhood
You'll find a lot of experience help and support here.
I really believe if it's meant to be, it's meant to be. If it's not meant to be something better is out there
If you and your ex have a good and strong relationship, then chances are he will be back.
If its not good and strong then he's probably done you both a favour....
If you both use the time to work on yourselves, it can only help the relationship if you two get back together again
