Using sperm donor behind husbands back

As terrible as it sounds I purchased sperm from a donor ( have not used it as of yet.)  My husband was previously married for almost 10 years and actively trying with his wife. It never happened for them. The month they divorced she ( his ex wife) got preggo by the guy she started dating ( they did dna test because her new bf had doubts) it wasn't my husbands kid. My husband believes he's the problem but refuse to see a doc. I'm so annoyed to the point I went online to a sperm bank and made a purchase. I obviously went with a donor similar to my husband but I feel so bad. I got it delivered to my parents home but I'm so afraid to go get it and possibly make the insert! I don't even believe I can return it. Opinions? And please no judging I really love my husband
