my bf moved and idk how to cope w it

so my bf moved to Texas about 2 weeks ago and I just have no idea how to cope with it. we talk just about everyday, but the feelings of sadness are still there. I keep in touch w his sister in law on fb and that's helping me a bit. i'm not worried about him seeing other girls, as he's not that type. He's too busy for that. Long story short, i keep doing things that remind me of him, going to the area of his house to remind me of when I'd sneak out there at 11pm and come home at 4am before my dad wakes up. How do i break this?
