I hate my husband's dog so much that I wish I had never married him
Is the dog that much of a problem? Would you really regret marrying your husband over their dog?
No, it's because my husband is controlling the dog so much in the house.
You shouldn't regret marring someone. If you have the feeling that you're unhappy in a marriage then you should think about getting a divorce.
Right, I'm going to hurt him by getting a divorce.
Getting a divorce over a dog seems excessive. You should at least talk to someone and get counseling first in an attempt to save the marriage.
