Why doesn't proctor go to salem to report what abigail has told him? why does elizabeth want him to go? why does elizabeth mistrust him?

1.) Because proctor doesn't have any proof of the affair and no witnesses were around

2.) Because she wants him to be honest and tell the truth

3.) Because he had an affair with Abigail and got caught / their marriage is going downhill because he hasn't gone to make an attempt to end it
