I think it's a fair response, and I can appreciate the truth in one's own life that leads you to write it. But this situation is a complex dynamic, no two situations are precisely the same either factually or subjectively. The same couple with a new child may stay close to one, drift away from another for totally different reasons that may not have one thing to do with intention or effort.

At any rate, I'm never too proud to reach out to old friends even if the time between attempts increases. Relationships may change again!
