Should I confront her?

Theres this girl, and she told me she liked me a week ago, after our first kiss. Then her and My friend chase got very angry at me for doing it and he was one of her best friends. Her, not wanting to lose him as a friend I hope, apologized to him, and now he is obsessed with her, but she is a girl who doesnt know how 2 talk to guys, and shes really nice to everyone. Even super fat guys think she likes them... So he is making all these facebook comments like I love youu Mary, and I wish You were Here (obviously directed at mary) and also he said "I cant wait to be with you!" As his status, which was again, directed at mary but when she said me too, he responded and acted like it wasnt directed at her. Hes obsessing over her and shes too nice too say no... She has been waiting for me to ask her out now, and last night we made out... But chase is very insistent on hanging with her. Does she want me to b the fall guy so tht she and chase can b friends still? I dont know... But we were gnna hang out tonight I think and I was either gonna ask her out or confront her on chase and ask her if she rlly means what she says and if she likes chase or not. (last week she told me tat she liked me, not chase) but tht was b4 they started talking again.)
