How can I get my man to have intercourse with me more often

OK so me nd my man have been trying to make a baby but lately he is always to tired or I go to bed by myself and it makes me feel unattractive. What can I do. I've tried so many things I just want to give up. I just don't feel like he realizes how much it really hurts me. What should I do or what I need help. Before I go crazy
