Well, i feel that if you go down the relationship path, the "I know you can't recall anything at all" line could be something like "my life started when i met you" kinda deal. Like he loves her so much, and he screwed up and cheated on her or something, and that's the information that can tear them apart. Also, he learned too hard how easily he could lose his partner. And if he were to just "whisper out" his secret he could lose her and that would "stop [his] heart"..... but idk, thats just what i put together......
