Admitting. It's a form of the verb admit.
But watch, as the word had and has a number of meanings.
1. To let someone in the door. "Admit him entrance, Griffith: but this fellow Let me ne'er see again." (Henry VIII)
2. To allow or permit generally. "Let me not to the marriage of true minds Admit impediments." (Sonnet 116) "We do remember; but our argument Is all too heavy to admit much talk." (Henry VI Part 2)
3. To assume a fact. "Admit no other way to save his life . . . but that either You must lay down the treasures of your body To this supposed, or else to let him suffer" (Measure for Measure)
4. To confess. "For me, the gold of France did not seduce; Although I did admit it as a motive The sooner to effect what I intended" (Henry V). Although this is a very common meaning of the word now, it was a rare one at the time. Shakespeare would be more likely to use the word "confess".
