Angry is a Understatement

Y’all help me out , my husband had an emotional affair on me ! He told me the truth when I asked him about it .. 🤦🏾‍♀️ which I expect nothing less ! But , lately I’ve been feeling really vengeful , i been wanting to cheat out of spite ? Is this normal ?? I haven’t acted on it , and I’m fighting the urges , but I’m soooo angry ! At first I was extremely hurt , now I’m angry and wanna get back at him ... I’m not gonna do that though , I Just wanna know is this a step to healing ???
