OP, I've been there so not judging...I don't want kids but there's something about being mid thirties that is quite emotional?
It may be the stereotypes we've been fed which encourage us to feel desperate.
Honestly I'm 40s now and look and feel great and actually feel freer than mid thirties due to current work situation! (Been dating 6 years younger).
I detect you're being quite targeted in the way you're looking?
Unless you've met someone and PROPERLY got to know them you have no idea how well matched you are, how they make you feel?
Alpha is a meaningless term...there's a lot of guys with good jobs who are weird and needy and hardly paragons of masculinity!
A few months is often when the cracks start to show.
Especially if you've just broken up with someone, you're looking for a perfect replacement.
I'd just start meeting people for a year - combine apps with real life, don't have any set views, just see what happens. Check into your own feelings. Treat them as friends first. Really get to know them.
Even meet women who can introduce you to new men! Just expand your life. I was thinking how nice it us with AirBnb and remote working how we can do a few months in different big cities! I'm hoping to do a season in London 😇
Forget thinking about what job they have (as long as they work and are not a total waster).
I've seen women "settle" quickly for men as they tick certain social boxes (good job on paper etc).
Often these older guys are single for a reason....quite rigid, difficult, sometimes undiagnosed ND, Ok as long as everything is perfect but not good otherwise.
I can see why the women do it - but it's not great later on.
If you are 100% sure you want children from a biological perspective you should have them with the youngest freshest bloke going.
