Please explain a little.

Question

Answer

The word "abdicate" have two meanings:
1- To give up for being a king or a queen.
2- Or, to refuse to be responsible for something. So, "abdicate" here in your sentence means that the person refuses to be responsible for these position any longer.

Answer

Hi,

It means that you give up your responsibility. Like you renounce to do something. If a parent abdicates all responsibility for his/her child; it means that he/she doesn't not assume his/her role anymore. He/She abdicates.

So your first interpretation “you failed to fulfill your responsibilities because you do not want it to do” is closer to the meaning of abdicate

Hope it helps...
