Everytime I make a female friend, I say to myself "no more friends"....im a naturally social, outgoing guy, who likes talking to different people. My problem is it feels like I'm friendzoning myself. Everytime time I see a girl I like or might like, it follows the following pattern:

1) meet girl and say "hi" 2) strike up a conversation. 3) continue the conversation. 4) become sorta "friends" - we talk, we laugh 5) ask her to do something together, she says "yes" 6) she doesn't give me any indication she is interested in anything romantic. She doesn't drop any hints, so I don't escalate. 7) we remain friends, which I can continue if I want

Where am I going wrong? At this rate, I will have a ton of female friends, and nothing more than that. In the scenario I described, it always feels like she has to give some indication for romance to begin. Otherwise it is just a platonic hangout. How do i get away from this?
