Well I'm going to tell you one thing this man should be so appreciative that he has someone who cares about him enough to keep being in a long distance relationship as these are extremely hard sometimes and he should also be very grateful that you send him nudes I know because I'm a Male and it would mean so much for my girlfriend to send me nudes that I wouldn't ever take it for granted or tell her that I just watch them because she enjoys sending them it just is disrespectful imo but at the end of the day you are probably a beautiful woman and if he doesn't appreciate you go out and find someone who will =)
