I think you can buy a cell phone, and try to write emails to your lg every half day when you feel tired to talking . Also, if you have time, you can write the letter to your lg, and send him some little gifts.
When you talk, you can put some boring things such as exams, homework aside, because talking those things through phone won't solve any problem. One's happiness could be two's happiness, but one's unhappiness would be better leave to himself/herself if he/she hope the other could be happy.
my friend bought a cell phone last year,he said it is free in the night,every night he chats with his wife,his wife is in another state,but it is also free through cell phone...can not believe it,but it's true..hehe...
many family plans offer free phone calls between the two phones regardless of the time, even in daytime, if you are in a family plan, the call is free.
