As I see it, one should not develop too strong of a bond to any given spiritual director or priest. If that bond progresses too far, it can disrupt both the believer and the priest. Worst cases become a near occasion of sin - not saying that is occurring here. Things change and we must be ready to change with them. Humans form bonds that are good within family and among friends, but can develop to a point at which they become unhealthy.
Psychologically, we can attach to persons or even things, but our prayer life should need only as much direction as necessary, or we risk becoming spiritually and possibly psychologically dependent upon that advisor. That might easily lapse into an unhealthy bond. It is well known that injured soldiers bond - even fall in love with - the nurses who attend to them. This same relationship can take place between counselors, doctors, priests and those whom they serve. I would carefully ponder this.
