I'm of the same age as your son
I've had troubles with depression for years, and it's possible that a chemical imbalance in his brain is causing him to act this way. Such depression can seem to come about for no reason, and cause people to act very differently than they normally do. Worst of all it likely won't fix itself, or at least it will be a long time before it does. It does sound like he's confided how he really feels to his girlfriend, if you and everyone else all notice that he acts so sad and she says there's nothing wrong she's likely saying what he wants her to as to protect him. Men our age aren't very comfortable talking about our feelings, I know that over the years whenever a friend or family member tried to talk to me about my depression I've always tried to cover it up, not matter how obvious it might seem it's likely he will always try to make it seem as nothing is bothering him, he might feel weak for feeling depressed. Or it could be that there is an issue between him and his girlfriend, which is why she would be in on it, but that's pure speculation so don't take that too seriously
All I can advise is to repeatedly approach him about it, but don't do it forcefully or suddenly. Be warm and loving, and make sure he knows you care about him and want to help him with whatever is bothering him. But if he gets offended or upset and still doesn't want to discuss it, don't press it, it won't help
These are just suggestions, and you know your son much better than I, so everything I say must be taken with a large grain of proverbial salt. But speaking from experience this is how I would go about it. I hope you're able to figure out what's bothering him, though if he's become clinically depressed than it's possible nothing in particular is, he's simply become disillusioned with life, overcome with feelings he may think he has no reason to be feeling. I know I've felt that way before, and it makes me feel guilty when it happens, which is how he might feel
