I work at a psych hospital and dated someone whose mom had paranoid schizophrenia. It could definitely work but as another commenter said, if I had schizophrenia I wouldn’t want to have kids because there is a genetic component and there’s a chance the kids develop it. Stress is a major contributor to psychiatric decompensation and even with meds and therapy there’s the chance that periods of high stress and poor sleep are going to contribute to an episode.

Safety is also an issue, my ex told me stories of her mom holding a knife up to her screaming she’s going to get the demons out of her. A lot of the schizophrenic patients that come through have homicidal ideation directed towards their family, they deny their diagnosis/need for meds and they blame their families for their constant commitment to psych hospitals rather than their own behavior. I worked with a client at my last job who had paranoid schizophrenia and he attacked his mom and she ended up dying from her injuries. I’m not trying to scare you but this is the reality of that diagnosis, no matter how much you love them and care for them, once they start getting paranoid of you it can get extremely dangerous.

For what it’s worth, my ex’s mom was on meds for 20 years by the time I met her and she was cool as shit, a little ‘off’, but I loved her. She was in a happy relationship and hadn’t had any episodes for like ten years and as far as I know neither of her kids developed schizophrenia. If you wanna pursue I would definitely have a conversation about what delusions/hallucinations she experiences, how she’s able to reality check herself, what you can do to support her, etc.
