I keep saying yes and then feeling resentful.
Common signs...
You may feel...
You said yes, meant no and hoped someone would notice the difference.
What might be going on
Resentment often builds when you keep giving more time, energy or access than you actually want to give. People cannot reliably respect a limit you have never said aloud.
Try this now
Choose one arrangement you want to change. Write the limit in one sentence, such as, I can help until four, or, I cannot take that on. Then stick to the sentence.
Reflection
I keep saying yes and then feeling resentful.
Where am I over explaining because I do not trust a simple no to be enough?
Did your actions match the limit you set? A repeated request does not mean you need to reopen the decision.
Something You Need To Hear
Why this card fits
Queen of Swords is useful here because clear does not have to mean cruel.
Practical point
You do not need a watertight excuse before a boundary is allowed. Say what you can offer and where it ends. Their disappointment can exist without becoming your instruction.
