<human>: Can you provide a brief rundown of the text in within 3 sentences?

So I am 25 and have a history of mental illness, and my family has an extensive history of mental illness. Well the other day I was talking with my SO of a year, about the future. Well the topics of children came up and I told him how I really want to be a foster parent. I feel it would be risky to have a biological kid of my own, I know the struggles I have faced and I do not know if I would want my own child to face the same struggles. Problem is my boyfriend seemed real firm that he wants kids of his own. I really don't know if I want to have kids of my own, but I do know I want to be a parent. While kids are no where on the radar in my life, the conversation struck a nerve with me. How do I bring the topic back up without sounding baby crazy? Also am I ridiculous for not wanting a kid due to the risk of mental illness. Keep in mind I'm talking sever mental illness.
<bot>: how do I bring up future child talk with boyfriend, don't want biological children due to family history of sever mental illness
