how do I unblock the names of the people that I blocked from my phone

I need the names from the people that were blocked from my phone ( iPhone 6 Plus ) all I got a few minutes ago was numbers and that don’t help becouse I don’t know their numbers! Mainly I need my husbands, I accidentally blocked Him& he is totally mad at me!!!!! His number is xxx-xxx-xxxx, and his number wasn’t even on the list it showed me that I blocked! As a matter of fact most of them I did not block, I might have blocked 8 or 10, they were at least 30 on there who I have no clue who they are !!!!! How can I get the names of people I blocked ( especially my husband! It used to show the names !!!! Why isn’t it doing that now?????????
