Why is it so hard to be heard?

So you're in a relationship, things went wrong (arguments etc), she decides to take a space (maybe around 3rd time in a year)... then you say OK and leave her alone. But because of your love and care, you're the one who always initiates interacting (about 4th, 5th day). She acts cold, you just take it down low... but you don't give up because you wanna fix things. Then why are we accused of "Not respecting their request of wanting to take space?".
Do we do wrong because feeling 4-6 days is quite long, or is it that they are just too stubborn to reach out themselves, but put the blame on us for reaching and not respecting. Are we in the wrong for trying because we care for our relationship? Or are they right for us violating their request? Does taking space really have a meaning or a certain principle, or should we take space as NO CONTACT at all? If we approach or take a step to test the waters, then why are we accused of violating? If we don't take any space, then this time why are we accused of being careless? Please someone enlighten me. What do we really do? AS I'M SO CONFUSED.
