You're right, this is a totally solvable problem. At least it's a little more believable for Peter not to offer a telepathic solution when Ben is saying "I need to move on with my own life, be my own person" instead of "I NEEEEED your MEMMMMORIIIIES, PEEEETER..!"

Why Ben isn't seeking some kind of telepathic solution instead of just...I dunno...hanging around, waiting for some solution to present itself, and hoping that a veteran superhero doesn't notice someone skulking outside his window (I get that Ben probably wouldn't trigger Peter's spider-sense, but that excuse only goes so far) is left as an exercise for the reader.
