<human>: My husband and I have been together for 7 years and married for a year and a half.  

I had health insurance on my own but due to the marriage we decided to consolidate into one plan.  He added me to his health insurance plan through his employer, effective January 1st, 2015. After having several complicated issues with my doctor's office, they told me that the birth date listed on my insurance is different than my actual birth date.  He apparently listed the wrong date, but got the year correct.  My doctor's office told me that I need to contact my health insurance to correct this.

I asked my husband about the incorrect date and he said that his fingers simply hit the wrong key and apologized.  However, the date was nagging at me, so I did some research and it is his ex's birth date.  They were only together for two years, whereas we have been together for 7.  They had a rocky relationship, and it did not end amicably.  He does not have any feelings for her whatsoever.  

However, the mix up still annoys me.  Should I say anything to him, or just accept that it was an honest mistake and let it go?

Can you provide a brief overview of the text?
<bot>: My husband can't remember my birth date but can remember his ex wife's.  I know he meant nothing by it, but I am still annoyed.
