Am i overthinking this? Need some second opinions

Hey so I met this girl a little over a month ago online and shes been through a recent breakup (a little before we first met) and since then weve been talking pretty much daily. Whenever we call we stay up late talking, watch shows, play games tg, even have slept on call a couple times in last week or so.

Now on one hand when we talk I feel I almost ask too many deep questions. I wanna know her on a deeper level but i also dont want to move too fast, be too invasive or be an interview/therapy andy.

The banters fun, convos are nice but i feel stuck in an area where i dont want to make it clear im interested since she needs time to heal(not my place to say but i wouldnt want to be just a distraction) from a long and rough recent relationship breakup but i dont want to be stuck in an area where id be just a friend.

Edit: the other night i asked if she was down to play in which she said shell be home in an hour but after decided to do her hair and by the time i got a response it was a few hours later and just to sleep. Probably insane to question friendship just off this but i cant help but think maybe i done smth wrong or have just been too pushy/annoying.

Maybe im thinking too hard especially since when we do call its normally always great. Some other insight would be helpful
