How many little “accidental” touches from a friend would it take before you start to pick up on it being something more?

My crush/friend who I used to work with I would notice numerous little “accidental” touches between us handing something to or showing something with our hands such as reading along in the Bible showing me the line as being read and keep lightly touching my finger and I would always have to move mine before hers and never apologizing for any of these touches either. When we would be around each other if she had to get by she would lightly just bump into me or lightly brush against me instead of saying “excuse me” or trying to signal me to move. Lost track of how many all of these “accidents “ happened but I remember it happened enough times to where I started to play a game in my head to guess if she would find a way to “ touch “ me somehow lol. I’m aware confirmation bias could be in play here, but I swear I’ve never experienced this with any woman/girl before unless we were dating or was obviously into each other. When we would sit across or by each other in the break room her feet would touch mine and I would always have to move my foot first. Happened multiple times , maybe she was clumsy or naive. I was mid 20’s she was 19-21 years old and she is very religious not sure if those details matter.
