Missing him

So me and my boyfriend are long distance. We didn’t see each other for two months and yesterday he came to visit. He stayed the night for the first time and we had the weekend together but now he’s gone home. He left An hour ago and I haven’t stopped crying since. I miss him so much already and my bed feels so empty without him. I don’t wanna sleep alone tonight 🥺. Any tips on how to deal with this? I’m currently sat in his jumper sniffing his aftershave and crying while eating some sweets. He said it killed him to leave because I cried and he felt so bad that he couldn’t stay to comfort me.
