awkwardly approached a girl for the first time. had some questions

have been seeing this shy girl 4-5 days a week for the last 10 months now. she did smile at me once, but im not sure if this was meant for me, so i just quickly looked down because im shy. we made lots eye contact after that so i took my chance and approached her.

we said hi to each other and i asked her name. i didn’t really know what to say so we just stood there in awkward silence for a few seconds.
this is where it got weird. i didn’t know what to say i asked her if she didn’t mind that im talking to her, to which she said no, and then i asked her if we could talk for 2 minutes. she said what i wanted to talk about. i froze up, said “never mind”, and left.

she did seem comfortable so im not sure if she is actually creeped out or not. a day after a friend of hers asked her about it and she said that our convo was normal.

however, the next 2 days she started to behave weird. she completely ignored me, not even looking at me, so i didn’t talk to her. however, the next 2-3 days she started to look at me again, but i didn’t react to it. i can see from my peripheral vision that she’ll look when im not looking. she also once checked check over her shoulder to see if im still in the room.

1. does she know that i was nervous?
2. did i come on too strong or creepy?
3. was my lack of experience noticeable to her?
4. some friends told me that i might have hurt her feelings, hence the weird behaviour by her the next few days. could that be true?
