Boyfriend in a huff with me for saying I was busy, please help

My boyfriend came back a day early from tennerife & gave me a call when he got home. He was fine on the phone although he never said that he'd missed me while he was away.

He said he wasn't sure when he'd be able to see me because he had to unpack, settle back in & see family, which was completely understandable.

My friend hannah was coming to mines for a girlie night in the day after he phoned, as she was going through a hard time & she recently had told me she was bi-sexual & had a crush on me. This didn't bother me in the slightest.

The girlie night was arranged for about a week .

The day that hannah was coming to my house I had a text from my boyfriend who apparently ' couldn't wait to see me', & he asked if I would go to his that night.

I told him that I was busy & that I was sorry, & asked when he was next free to see me.

He normally replies okay & gives me a different day to see him however instead he asked me what I was doing & who I was seeing. I told him about seeing hannah for a girlie night in & he flipped & put words into my mouth by saying ' I thought hannah freaks you out cause she fancyie you'. I said She didn't & that I was sorry that I couldn't get out of it .

He replied ' Ok.' without any kisses & from then on he has been in a huff with me. This has went on for about a week.

If he had only asked me the day before & I could have changed my plans with hannah.

We have been going out for a year & a half, but he has never acted like this.

please help me & give me advice on what to do or about what he might be thinking.

I don't think I've done anything wrong. :(
