<human>: Can you summarize the given text in a few sentences?

First of all, I would never consider having an affair.

My concern is, my husband's family has a ton of health and mental issues that span back generations, and also have issues of not knowing who some relatives' fathers were, etc. There's even some suspicion of incest in a prior generation that was just never confirmed. He comes from a really dysfunctional family.

We both want kids, but I'm terrified of passing something on that will make the child's life harder, and I've been thinking a lot about adoption, or sperm donors. But I also am scared because I don't know if he will love and treat kids that aren't biologically his or ours the same, so I never bring it up.
<bot>: Husband and I both want kids, but I don't know if I want to risk passing on his family's bad health. Should I bring up other alternatives?
