Answer Details

The best options to fill the gaps are "mature" and "matured". The sentence suggests that when the speaker first met the person, he was not very mature. However, over the years, his character developed and he became more mature. Therefore, "matured" fits in the second gap, indicating that the change happened gradually over time.
