Anyone in a long distance relationship, how do you set your rules of communication?

How often do you guys talk and how long? Bf and I talk every day…more than twice usually. We make it a point to talk before bed and say “good night”.

Have you ever been able to not get a hold of your significant other…how do you avoid things like that? This was a big deal…so he keeps his phone on him at all times (tries to), and if his phone dies charge it ASAP, but at least call to say good night no matter what.
Are you in separate time zones, if so how do you work that out? three hour time difference. It’s hard to schedule a set time when he’s sleeping and I’m busy…then he is busy and I go out at night…and when I’m going to bed he’s ready to go out at night. We talk when we can.
