I like this girl but don’t know what’s going on right now. Any advices?

There is a girl I really. Her friends kept telling me she likes me and asking me about her and she even rejected boys because of me. I asked her out and she said yes. We kissed few times and all was fine. We had to cancel our first time out because always one of was busy because of work or holiday but mostly she was the one. Once I asked if she’s free she said no she’s at work and she said so other day so I guess she wouldn’t say that if she didn’t want to go. Then her friends started saying things like she’s complicated, they’re confused of her and maybe I should give up on her. I asked her if she really wants to go out and if she would tell me if not. She said she would tell me if she didn’t want to go. So we went out and it was fine. Then her friends started saying these things again. Then I met her friend from boarding school and she said she talks about me often and likes me. I texted her if she’d go out again someday and she replied that this week she can't and then school year starts and she’s in boarding school so I said I meant like in the future and she said we will see. I don’t know what to do know and what to think. Do you have some advices? Thank you.
