Confused, hurting & feeling ugly

He came over to have BBQ dinner with family (1st time) on Good Friday & then on Easter Saturday we went looking at display homes... when asked by the sales people he said "we are just starting to look/ this is our first day of looking". After this I asked what his plans were for the rest of the day... he mentioned that he'd be having a nap & then doing some work on his computer. Later that Saturday afternoon I was bored as have just had Gall Bladder removed one week ago and wanted to do something except for sit at home. After texting a couple of friends I found one who was going to a dance night & even though she was concerned about me going I told her the surgeon had said it was ok for me to dance, I just had to listen to my body for any signs if it was too much I'd stop. Turns out that she said to ask this same guy (he was going dancing too!) if there would be room in his car as he was driving... I did this without making any issues or questioning why he told me he was doing something different (on the computer!). There was a group of friends going dancing that night & it was arranged that morning - why would he lie to me, was he just not mentioning it because he thought I wouldn't be able to go because of the surgery & he didn't want to rub it in my face or was he looking forward to time without me and prospecting other girls without me present..?? On the way home we were jovially talking about being positive & giving compliments to people (daily)... he asked if I had given a compliment to anyone that day and I told him I'd given a compliment to my nephew. Then it was his turn to mention that he'd given a compliment to one girl at dance (he'd danced & hung with her for most of the night) & then he turned to the lady in the car & said "I gave you a compliment earlier tonight as well saying that you looked nice, didn't I?" - WOW, that hurt... there I was sitting in the car almost in tears now & feeling pretty ugly, but I didn't let him see how much he hurt me in that moment. I am confused & really hurting as how can he go from looking at houses with me to being so nasty in a couple of hours. I really wanted to do something that night with someone & didn't mean to catch him out lying to me - He was busy "on the computer", which is why I contacted other friends to do something (he was my first choice)... I made no issue of it & was just happy to be out with friends that night. The next day we (dancing friends) all met at a local festival & I text him to see if he was going as I didn't want him just to turn up surprised to see me there. He said he was going later that afternoon & I mentioned to let me know when he was there & I'd tell him where we were... he did this & things seemed normal between us - his eyes followed me, hung near me, etc... I asked him for a lift home & he obliged - I asked what he was doing for dinner & he said that he'd be eating what was left over in his fridge, I mentioned that I wasn't sure if there was anything in my fridge (normally he would have asked me over as well or he would have offered to take me to get take away on the way). He said "surely you'll find something in your fridge" & proceeded to take me home... I asked about going to the beach the next day as earlier that weekend we had already tentatively planned that - he said he'd see how he felt & if we got in touch "maybe before Tuesday" otherwise it would be on Tuesday I'd speak to him. Now it is Tuesday & we have a business function to go to together tonight... I'm going to leave it for him to contact me about the transport arrangements as it is 1 1/2 hour drive, but I'm still confused & hurting & feeling ugly. What is going on here, please help!
