I'm in this exact situation in my early thirties. I hold onto the hope of meeting a man who is kind-hearted and wants a family.
Years of dating have left me with the somewhat pessimistic (but I like to think it's just realistic) view that relationships don't have to last forever, and that finding someone who will be a good father regardless of whether we're a couple longterm is ultimately what's important.
Not that that's my goal, I'd love to meet someone who I could build a family with and stay together longterm to raise children, but from what I've seen in my own expereiwnce and around me, people in longterm relationships / marriages have put up with a lot of bad bahviour (both female and male friends).
I have ended relationships because of behaviour that I couldn't look past (cheating, drug use, sudden interest in Andrew Tate...) which I see others tolerating, so maybe my 'fussiness' will ultimately mean that I don't have a family. But that's a sacrifice I'd make.
Sometimes it feels unlikely that I'll meet someone and dating apps certainly don't seem to be the way forward, but I have hope! I often ponder adopting a child alone but would need to give that some more thought.
Great question to get people thinking, interested to see other thoughts.
