Thank you for including this tidbit. I'm a man in my early 30s interested in having kids and recently discovered that I've poorly vetted my 5+ year SO's interest in having kids. Her "yeah, I'm hypothetically interested" has become "hard not interested".
The requirement to break up with her if I want kids is deeply painful, but the real source of my dread is the feeling that I won't then be able to find someone good in time. I'm very glad you found someone good to have a family with.
