Relationships bid for attention. A request demands a reaction: either share or dismiss.
Some people become vampiric, needing you to sustain them. (And vice versa.)
Your responsibility is your life, not theirs. Do not give improperly until you become resentful; do not be hurtful.
Acknowledge that both people are individuals with boundaries, and then you can enjoy the generosity of kindness for the gift it is, rather than a compelled demand.
