Hi loves i’m relatively new to this app but i need help/advice

My boyfriend of 6 months works/lives 12 hours from me and during uni months he stays in the main city (from australia) So since summer holidays are coming up, he’s going home for 3 months and will be in the city as much as he can, he gets free flights from his company. 3 months is a long time to be away from him but any tips on staying busy and just making time go faster when he’s not here. Longest time we’ve been apart so far is 3 weeks and it was complete hell for us so just any tips on keeping busy and not missing him as much as i know i will xxx
