A friendship where only one person reaches out is a hobby, not a relationship.

Initiation is effort, and when it always comes from one side, what exists is closer to devotion than to mutual connection. This is not always coldness on their part; some people genuinely never initiate anything with anyone and are pleased every time you call. The question is whether that is enough for you, which only you can answer.

Try stopping for a while without announcing it, and see what the silence tells you. If nothing comes, that is worth knowing gently rather than bitterly. And put some of that effort toward people who reach back, since being reached for is not a luxury.
