Propa confused!

Basicly I’ve been friends with this girl for about 8 months now, since the day we started meeting up shes always told me she has never and wud never lie to me, the things we do together are the kinda things couples do (apart from have sex and kiss ect.), she told me she was seeing someone but then she asks me to go abroad with her (just me and her) and when I said I couldnt get the time off work, I asked her why doesnt she take her boyfriend and she told me she didnt want him to go with her. And the other thing is I’ve always had my suspitions about her sexuality bt she always promiced me shes strait and all of a sudden a few months ago I started to want more then a friendship with her and she knows this, a few days ago she tells me 1 of her biggest secrets and finally admitts that she bisexual and that she has been for the past year or 2, which 4 sum reason has made me want her more, and also when she describes the type of man she likes as a boyfriend she describes it in exactly the same way as she describes me, and when its just me and her alone she gives off the impression she wants to be a couple, but when were out and about she acts totally different as tho we are only mates (not even close mates), its at the stage of all of her friends and family think were a couple and dont beleve us when we say were not. But she says she only sees me as a friend.

I dont know what to make of it because a lot of women have told me she doing it to test me but im not really sure. Help me out please.
