Confused, embarrassed hurt by male Taurus 5yr BFF

Background: Until 3 years ago we lived in the same city. We both went to grad school, he just returned to the city where we met last year and has been pushing for my return ever since. Last summer around my birthday, I realized that I have feelings of more than just friendship for him. I told him, he said "I think it's cute, but I don't think we should go there". "I don't want to risk ruining our friendship". I was somewhat embarrassed, but he reassured me that he still sees me the same way and that I'm still the same to him, not silly or crazy. So until February I had distanced my self a bit. We stopped talking about who we're dating and ceased our very touchy/feely/huggy ways towards each other almost completely.

He has, in very subtle ways, been hard pressed about me moving back to the area. So much to the point that he has been trying to help in my job search. I've even started to feel less awkward and have returned to letting him know that I love and care for him.

A month ago (my last visit, I stayed with my old girlfriend that lives in his building) he looked me in my eyes and said, you are more than welcome to stay here next time (he knew I would be returning soon to look for a job). Later that night I told him via text that I would stay at his place when I returned.

Few weeks later I booked my flight back to the city. I text him the date of my arrival and I told him to call me. He texted me back: "sounds good", I'll call you a few days when work/stress simmers down. We don't speak over the phone about this trip until this weekend. Since we have been playing phone tag for the past two weeks I took his call while out catching up with my class friend over dinner. He tells me that he didn't know that I wanted to stay with him. That it wouldn't work because he'll be out of town for work. Then he says that he met a female, "two weeks ago" and wants to develop trust with her and it wouldn't look right if I was staying at his apartment. Since I was with friend, I just told him Ok and that I would figure it out and call later.

I began to think about it later. This guy open his home to everyone, especially his friends. He has gone so far to let them throw a party at his place with him being out of town. He's always been like you can stay here, you know my place is a hostel. He's been pushing me to move back. He's been my BFF for like 5 years to turnaround talk to me like I'm a random chick made my heart dropped. Why is doing this to me?
