Why are men always expected to be the ones to reach out?

After having many female friends I've noticed that in my experience woman do not reach out to men unless they are a potential romantic interest are already one to begin with. I've seen this multiple times where if I don't talk to a girl who I'm friends with for a while and decided to talk to them the topic always arises on who should have reached out first. And wherever I ask the girl why they didn't reach out they never have an answer or swiftly changed the topic. This isn't always the cases but it is the case far to often. Are men seriously expected to do everything for women bin there interactions nowadays? I feel like I'm holding a babies hand all the time.
