That's totally alright if they won't reply you back. It's okay.
Just take a deep breathe, hold on for a second and then exhale. One day, they will. Lady! Just make sure that you wish them on their birthday.
Lady! Don't say yes to anything that he asks for. No more pictures without clothes or with clothes. Respect your dignity. Know very well that even though he is away, removing your clothes here in front of screen is not going to stop his craving there for 'you' or 'sex'..so!! Stop!! If he gets angry, let it be. Just colour each one when in front of each other. Don't ask for nudes when far away. It's the era of net you shall always be safe.
