I suppose it’s the most “Fi-style” approach to the situation, in that Fi is about defining one’s own agenda/values and respecting the agenda/values/autonomy of others. Of course, it can be taken to extremes. INFPs sometimes get caught in the trap of not wanting to burden others with their needs and going into avoidance mode; but then the situation increasingly becomes about conflict-avoidance and important issues go unresolved.
IOW, the standard INFP could try to be better at confronting people (sitting down and working out conflicts directly with people) or taking the risk of opening themselves repeatedly to unresponsive friends with the ultimate aim of establishing new modes of connection and interaction.
But in your case, you seem to have good reasons for choosing the route you’ve chosen; also, I would never accuse an ESTJ of being conflict-avoidant or of being afraid to put themselves out there with others. If anything, it seems highly appropriate for an ESTJ to use an “Fi-style” approach with Fi-Doms.
