Taurus man keeps changing his mind?

I'm an Aquarius. This Taurus man who I met a year ago at work, shared with me his lifelong fantasy as he claimed, of wanting to get spanked while restrained. He kept going back and forth getting me all excited that we would actually meet up and do it. (We live in the same state, but different cities, few hours away). He would send me texts like "Come up," "I wish you were here," "We can have some fun," "too bad you're not here." Then out of the blue, he says "She's out of town for the weekend and I have the whole house to myself lol."

The weekend passes and he messages me saying he doesn't want to jeopardize anything, but still wants his fantasy to happen. I told him we could do it so at least his fantasy is fulfilled, and we wouldn't have to keep in touch after that. He refuses and insists that we keep a regular friendship. He changed his mind again and proceeded to sext me few weeks later. I didn't sext back, and asked him why doesn't he just ask his wife to spank him and he tells me he doesn't think she will be up to it. I'm guessing there's no communication between him and her or some other thing because why keep something like this to yourself in a marriage? He went back and forth again and claims he really just wants to be platonic friends this time. I didn't believe him and he keeps saying he really means it. I asked him why did you send all those sexts before and he snapped at me saying, "omg don't ask me about that!!" His definition of platonic friends is that we'll rarely talk and hardly ever see each other now, but if we ever do run into each other again, he only wants to give short hugs and that's it. How is that a friendship? I don't even work with him anymore, and I kept in touch mostly through text with him until today. I blocked him and then unblocked him.

I did read up that Taurus and Aquarius could butt heads, but I'm not someone who just gives up on a friendship, if I can even call it that. I'm not sure what I'm asking for here: I guess some insight about wtf is he about?
