Please help

Hey guys :)

I told my best friend that im bi and im really relieved that she is really supportive of me. However, a few minutes later, she started asking me whether she is straight and i told her that i didnt know. She kept asking me and then decided she was bi too. That was fine and i supported her.

One day my other friend ask us what our boy types are since she straight. I told her my type while my best friend was hesitating. We were all expecting her answer but she shook her head and whispered to me “how about girl type?” (My other friend didnt know shes bi) she kept doing that whenever we talk about boys and honestly its getting a little annoying. She said shes bi yet shes acting like she boys have cooties or something and for sure she wont like them she will only like girls.

After telling me shes bi she had also said that she wouldnt mind dating me. It feels like she isnt bi at all and that shes either a straight pretending or telling herself she likes girls or that she is lesbian.

What do you guys think?

Thank you (ง •_•)ง
