> becoming a parent will lead to some sort of change in worldview or who you are, and that’s not always compatible with the friends you had
This is it. Parenting drastically transforms you (your behaviour and values) for the next 18 years at the very least. In purely behavioural terms, you become someone else. Expecting people to hang out with a stranger (behaviourally speaking) of the basis of shared memories is odd. You share memories with your 19 year old self who would most likely be more interested in hanging around with others around his age than with you. No different for friends
