The problem there is that the law would make him have responsibility, if they knew his identity of course.
It is a difficult decision to make, though I admire your determination and respect your choice.
Your answers from the guys tell you that you probably picked the right ones to ask, because they genuinely would feel a responsibility.
It is a conundrum isn't it. I think I would feel the same. Though at my age now it might be ideal, because I only have limited years left, but even then I'd think is it fair to a child.
My current virtual gf has made it plain that when we do eventually get togteher, (Covid allowing) she wants many kids. I'm willing now if we get the dough together to give them a good life after me, but there was a time that I would not have.
It is not an easy decision is it?
I hope you just meet the right guy.
