I'm 43... 44 in a few weeks.
I have a 7yo daughter and a 6mo son.
I never saw myself as a father. Kids were never part of the plan in any way.
I can tell you, and you will never KNOW until you have a child, it is the meaning of life.
Yes, you will have less money, less freedom, all of that, but really once the child is there you never feel the sting.
You will find a new meaning of love that is unattainable in any other way.
Forget all of your own selfishness and take the dive without hesitation.
I know parenthood is not for everyone, but it sounds to me like you will have regrets if you don't.
It's worth it a million times over.
