Hi Mailo,
She lives 5 hours away from you and the both of you won’t be able to see each other that much until you are both on another vacation.
This is not a good foundation to go about pursuing a romantic relationship with someone.
Though you may have fallen in love with this girl that you met over vacation, the emotion of being in love is often not enough to help you navigate the very challenging waters of a long distance relationship.
Be grateful for the experience that you had over vacation.
However, leave it at that.
Using her Snapchat and number to try to pursue a romantic relationship with her could make the next several months of your life incredibly difficult.
It is best to avoid contacting her. This way, you don’t fall into the trap of trying to make a long distance relationship where the both of you will barely be able to see each other work.
