Confused

I was dating my boyfriend for almost eight months. At first, everything was nice. He was really intimate, trying to do everything to impress me. He was buying me flowers, answering my calls right away, even before I asked him to. He was always trying to make me happy, and everything was perfect until one to two months ago.

All of a sudden, he started complaining that he can't answer phone calls right away, or maybe he wouldn't answer my call if he was at a strip event for five minutes, even though he knew it would trigger me and make me anxious. He said he wanted to be alone, and we had some discussions about it because I was wondering what happened and why he was behaving totally different.

Last night, he texted me, saying he noticed the triggers and would try not to do that anymore. Today, he was with me. We finally met after not seeing each other for a week. He stayed at my place for a couple of hours, and then suddenly, he said he needed to go to a VIP lounge to meet his friend. I was really surprised, and I asked if I could come or if his friend could come to my house because I've never met any of his friends. He said he didn't think I would have any clothes that fit their dress code, and he wanted to meet his friend there. Then we had a fight, and I decided to block him from everywhere. But somehow, I feel manipulated and used.
