Husband just said something is it questionable? Or am I just being too sensitive?

Due to breastfeeding and dryness we have not had intercourse as much as we used to pre baby etc. it seems like my husband even with lube doesn’t want to. So he just told me an old friend from high school days has been making cakes and baking stuff and they look really good and we should try it for a bday etc and showed me pics and he was like, “oh yeah you’ve seen her before, it’s funny I remember this but remember when I told you I knew the girl at the pizza spot a while ago that we go to and she wasn’t wearing a bra?” I’m like excuse me… no I don’t remember that —___— . Such a guy thing to remember and say. He’s like she’s not my type. I’m like okay what’s your type? And he was like “you, you’re silly.”

Why would he say this and remember that? Seriously…. I already feel undesirable because I feel unwanted with limited intimacy and stuff…. Postpartum etc. am I being too sensitive?
