If you fear you have been abusive to a partner, what can you do?
a) end all relationships for at least a year
b) accept that people can't change
c) be patient with yourself
d) find out why others make you abusive

Explanation:

This is the answer that most fit, because it's impossible to end all relationships in your life. Finding out why others make you abusive means that your are blaming others for your behaviour, if people even make you angry some how, you need to have auto control, being abusive is a personal and individual problem.

Similarly, accepting that people can't change, implies an elusive behaviour, which it's never gonna be helpful if that person want to get better.
