Guys, Help me UNDERSTAND?

I can think of two possibilities: One is that he views the way he loves as really special and beyond what he assumes other people feel. He may believe something like this, although it's unlikely to be true. The other possibility that comes to mind is that he has made choices or sacrifices to be with you that he chooses not to tell you about. That one seems much less likely.

Since he keeps saying this, you can ask him why he thinks you wouldn't be able to understand.

[Effably]

You clearly can not understand this. We can't explain it to you!

Its just a way of expressing that the feeling runs deep and, likely, very intensely. Don't overthink it and just reciprocate some of the romantic gestures sometime. If they do happen.

He is saying that he loves you more than he can adequately express

[Iron_Man]

He’s really into you
