Get rid of everything that they gave you because whenever you see it its going to remind you of them! & Just make things baddd. Do NOT have their phone number because you will end up calling or texting them sooner or later if you miss them.. Delete it if you do! Don't communicate with them at all the more you talk with them the more you will fall in love with them again.. If you see them just go the opposite way so you aren't near them!
