<human>: We have been dating for about two months now and over the past three weeks, he is becoming increasingly more tired and sad. He is also never "in the mood" and claims there is nothing I can do to fix it. I try everything he asks to make him happier, but nothing is working. If I stop making the first move on him, nothing will happen between us for weeks at a time besides a goodnight kiss. Whenever I try to talk to him, he refuses to speak or make eye contact. He only claims that he is "not depressed and only sad because he is a realist". Whether it be the stress of college or depression, we both just miss the fun we used to have together, but he doesn't seem willing to make changes or admit he has a problem.

Can you condense the text into a few key points?
<bot>: my boyfriend is exhibiting classic signs of depression and I don't know how to help or get the relationship back on track.
