my boyfriend lives in his Country of Egypt, we met on facebook but havent met in real life yet & he's working on his passport & visa to come to America to marry me- he was the one that found me, recently I tried looking up on my boyfriend's facebook messenger to see if he was "active" or not.. because he was supposed to be sleeping during the night to go to work the next day or other days, and plus I know his hours when he supposed to be sleeping.. and because I know his hours when its am night time there and when it is pm daylight here in America, so my main question to you is.. does it still show "ACTIVE" with a round green light ON even though you're NOT using facebook or messenger???.. because I see my boyfriend "ACTIVE" during the nights many times.. I asked him about it who he's talking to during the night, and he tells me NOBODY!! he tells me "when his WIFI is ON" thats why it shows "ACTIVE" and that it connects to the phone thats why its showing "ACTIVE" so is that TRUE??? or NOT??? I Really want to know if he's telling me the truth, so thats why Im writing you to verify if it is true or not?? before I start thinking about him that he's lying to me and I dont wanna think that yet.. before I hear it from you the way this system works exactly, so I ask you nicely and directly "PLEASE" let me know as soon as possible, im really hoping to hear from you very soon, I REALLY appreciate it.. because my opinion and understanding is.. when you actually log in to facebook itself or using messenger.. so thats when it shows "ACTIVE" forsure.. but he's telling me even though he's sleeping and not using his phone- meaning that he's not logged in to facebook or messenger and tells me it still shows "ACTIVE" because his "WIFI" is ON thats why.. so I dont know if I should believe him or not and want to find out from you if he's telling me the truth.. and so thats how the system works or what??? and like I said "he tells me it still shows "ACTIVE" even though he's NOT using his facebook or his messenger.. and when I see him "ACTIVE" during his sleeping hours.. it shows- Active * minute ago.. and then Active again.. and then Active * minutes ago.. and then Active again.. and then Active ** minutes ago.. keeps going on and on like this.. so anyway im just explaining how I see it during his nights when he's supposed to be sleeping during these hours and telling me all this which I dont know if I should believe him just yet or think that he's lying to me.. so PLEASE write me back soon and tell me how this system works, Thank You So Much!!* Love Mary
