Crazy question, and I haven't thought this through or spoken to my partner about it so don't take it too seriously!
I am much older than him and can't have kids. He was undecided about having his own children but we got together anyway and he is happy with me.
I have always felt a bit guilty about him not having the opportunity to have his own children and while pondering this I wondered if he should try and have a child with someone else. So my crazy question is this. Could he find someone who is single and wanted to share parenting with him. Maybe someone who hasn't met the right person or who is gay? Is this a thing and has anyone ever heard of this happening in real life?
