Long: Would you divorce your husband/wife if they gave you HIV?

I'm sorry if this becomes a long post. I'm just so confused. I was a virgin before marriage and I thought my now husband was a virgin also. We both got tested early in our relationship just in case things led to sex before marriage. (We have been together for 4 years, married for 1 year.) We were both STD free. I've only had sex with him and my doctor told me I am HIV +. So either my husband wasn't a virgin or he cheated on me. Possibly even both. My question is would YOU get a divorce? Any advice would be helpful. If I need to update anything, I'll make a separate post because I want to keep myself anonymous. Thank you.
