I think it would be fair to say that we all have a tendency to take things personally. It's just that some of us have a greater tendency than others to do so. And, when it happens, some of us are better able to deal with it within ourselves than others.
Taking things personally is never healthy in any relationship: employer-employee, friend-friend, husband-wife, partner-partner, parent-child, . . . for a number of reasons. One main such reason is that, if you do take things personally, then your feelings will continually be at the mercy of others - whether they attacked you personally or not. That is never healthy in a relationship, and it is no way to live!
