My (F22) boyfriend (M25) got his own apartment and now I’m homesick for him

He temporarily lived in my apartment for about 5-6 months. Didn’t wanna live with his parents so he asked if he could stay with me til he can afford his own apartment. Yesterday was the day he left and he literally lives 2 minutes away from me but I feel so sad and homesick, I’m all alone in my room and it’s so quiet. I can’t wait for the day we both can live together and have our own place. I’ve already signed the lease 4 months ago, that’s why it wasn’t an option to move in together and I don’t feel ready yet (we’ve known each other since Jan 2021 but didn’t get closer until sometime early this year so it’s still fresh). I’m gonna see him soon but I’m just so sad (I’m on my period too so lol). I forgot how it’s like being alone in my room, but I’m sure I’ll see him again. Has anyone dealt with this
