I just turned 37 bro.
To me there are no Cons, she is the best thing that every happened to me.
My split with my Ex has cost me everything, my house, my career, all my savings, moving away from my family and friends and you know what, having that little girl in my life has made it all worth it!!!
The biggest thing I have to learn is that I can't live for myself anymore, I don't see that as a Con though.
You will know when you are ready and you won't regret it.
