Why is love so painful?

I have been in this relation for 2 years…he is now in another country…my boyfriend doesnt have job…so he cant call me because of money.so I call him whenever he gives me misscall.if he give me misscall at 3 am at nicht I just call back him.no matter m sleeping or not..I just wait and wait whole day when he will give me misscall!!.I cant give him call always because he will not pick his phone…bcz he has 1 roommate who is 40 up age..my boyfriend feels uneasy to talk with me infront of them..my boyfriend can send money to his mom and dad wh already have lot of money…he gives them call.but he doesnt call me…he says he doesnt have money..if so then how he call his family..his family is also in my country..he doesnt have net in his house.so he often comes to cyber cafe..but he don’t tell me to come to msn…he just come to check his mail.anr watch vedioes..strange!!!he didnt ask me ever how I manage money to call him!!!I always beg him to my god…each and evey moment of my life I miss him..today he gives me call and I was in my shower..so cant call him..so he got angry and not talking with me..he is saying that he call me from card phone I didnt pick and the cut the money for making call…so he is not talking to me..not giving the reply of my sms..ITS TOO PAINFULL…Y M NOT GETTING THAT LOVE WHAT I DESERVE!!
