4 months gf, 7/10, amazing at sex.

After sex we were cuddling in bed and she was touching my body everywhere, then she started making fun of my hands for being small. Here's how it went:

Her: woah your hands are so cute Me: small smile thanks Her: they're so tiny hahah Me: ignore, no reaction Her: these are such small hands haha Me: then they fit well with your breasts

She got silent and mad afterwards, then I had to go and left. She didn't say anything to me. No response. I didn't let that affect me and left.

She told me months ago that she doesn't like having small breasts and that she hates it, so me pulling that line on her must've been rude, or not? What do you think? She's mad in love w/ me by the way. This situation happened 2 hours ago.
