Am I the safety guy?

This girl and I know eachother for a long time, we initially met because we were into eachother but that eventually flowed into something I can only define as ‘more than friends’ but we just say we are good friends.

Now she has two more male friends, one is gay and one is my best mate. She is much more extra with me and my mate always said the two of us could end up together someday.

Now when we’re out of touch, she eventually comes back into my life somehow. Last time we were out of touch for over a year and then she texted me just a day before my birthday.

Well why I am going here, when I give her no attention or I am unavailable and she is she chases me hard (almost instant responses, wants to see me) but when I give her more attention she starts to hold back (slow responses and whatever). Now we had a month going on of quick responses and when we saw eachother in person that immediately dropped. Now everytime we see eachother in person we have a great time and sometimes she makes me feel like the only guy in the workd but her behavior is inconsistent, maybe I give her mixed signs too.

But all her coming back and whatever makes me feel like I am her safety guy. Someone she checks she could still have if it doesn’t work out and on the other hand I think she has never been sure herself about us, just like me. We never got closure but I think we are both not up for the conversation.

Any advice would be lovely

Somewhere in high school she was really into me again she said but she told me this 5 years later.. and this was in a time i was unavailable.
Her masking everything as being friends really doesn’t help
