This is a very common question for older students, no less younger ones, and I commend you for considering it. While there are so many variables involved in making this decision, there are equally as many that are unpredictable in the future. That is, whatever decision you make now is the right one. The fact is, assuming you feel boarding school represents the best fit for your son now, there are plenty of ways that you can maintain - and arguably strengthen - your relationship while he is there. This can involve everything from parental visits to visits home to trips together to more frequent (and different kinds of) communication while there. Boarding schools typically offer many ways to address this common concern, and I highly recommend asking this question on your visits. Talk about this with your son, ask how he feels about it, and empower him to work with you to minimize the chances of this becoming an issue. Working as a team, you are sure to open up lines of communication that may not have even existed before.
