Boss acting funny about my wedding

My boss likes hearing about my wedding. He isn’t married but it’s headed that direction for him with his g/f. We just kind of chat about it here or there, mainly to make fun of how expensive weddings are. Originally I had planned to cater it myself(I’m a chef) but my mother talked me out of it.
So I started looking at restaurants that would just drop off the food. I was talking to my boss about the options I was considering. He said hey why don’t you get the food from work? I could get a big discount. I said I’d think about it. Honestly I thought about it but I just don’t want food I’m around all day at my wedding and we have severe dietary restrictions for some guests.

So FH and I found a restaurant we were going to use and my boss brought up the offer again. I said we appreciate the offer but we had something different in mind.
The restaurant idea fell through, something hidden in their contract. Anyway. We ventured on and booked an actual caterer with vegetables she grows from her garden, her food was right up our alley and hey we get staff to serve it at our wedding. Perfect!

I told my boss about it and he just got this kind of hurt expression on his face and said he’d planned to just give us the food from work as a wedding present.

Oh.

Well now he looks kind of bummed out anytime he overhears anything about the wedding(lots of girls are getting married so we’re always chatting about it), he doesn’t seem to be interested at all anymore so I don’t really bring it up. This has just made things awkward.

I feel really bad.
