I'm married but I'm obsessed with my coworker
Why are you obsessed with your coworker?
Because my husband is ignorant and never shuts up
You are disrespecting both yourself and your husband by cheating on him with your infidelity wishes. You should cherish the relationship that you have or get a divorce if you are not interested in your husband any more.
I hate that guy. I'm just using him for money and authority.
Even if you are fighting with your husband, it doesn't mean it's okay to obsess over another man. You are always expected to be faithful in a relationship.
