I'm losing my mind!

Help! SO coming back tonight after a long 6 weeks apart. I'm absolutely losing my shit. It's been radio silence for 2 days. I sent him nice messages "have a safe flight, excited to see you" etc. and nothing! I can't get a single word from him for two days. I just can't deal. I really don't want to make it awkward when I pick him up later but I'm borderline hurt. Im not even sure if he'll be happy to see me 😭😫 any tips on what I can do to keep my cool when I see him? I really don't want to mess it up.
