Flirting

He flirts but I'm "not his type"?

Ok so this is a long story but I'll just include the important facts. He is in his mid 30s and I am in early 20s. He works in a restaurant and I'll refer to him as A. He works with two other men, (B and C). They are all roughly the same age. I have a huge crush on A and I know at some point they have all flirted with me. B and C have admitted before that they "fancy" me.
Me and A flirt quite a bit. Examples of his flirting include complimenting my appearance, teasing me, slapping my bum, making comments about my figure (you have big boobs, nice bum), telling me I'm gorgeous), almost appearing jealous when I chat/flirt with B and C.
I talk to B on Instagram and he's always telling me that A or C have said something about me. He told me that A said he would sleep with me. Now, I know that A likes blonde women. I used to be brunette but since going blonde he has been more flirtatious. He also told me that he loves big boobs (I am quite well endowed..). Basically I am a blonde with blue eyes and a curvaceous figure.

However recently B asked A if he fancies me. A said no because I'm "not his type". After this, I went in there and they were smiling at me. I am very confused right now..
