Is this a sincere apology?

My MIL was over and asked about some new shoes I got my son. I showed her and the price tag was still on and it said $19. She said OMG $19?! Wow! And I said ‘wow’ good, or ‘wow’ bad? And she said well for how they look and smell and feel, I think $19 is a LOT!

I just picked out these sneakers for our upcoming vacation and like them very much. They’re from a store similar to Target. My husband was with me and we both were sort of offended by her comment. She has a long history of criticizing me and putting me down and I’m trying to deal with it better.

My husband told her after the fact that what she said was sort of rude. Then she texted me this. I think it’s a real apology but the ‘I’m sorry that I upset you one more time’ makes me feel like she’s calling me too sensitive again, which is a big issue we had last year.

“(My name), (my husband’s name) explained me that I sounded rude when I was talking about the sneakers. I apologize about it. I didn’t mean anything bad. I respect choices that both of you make.

I’m sorry that grandma got you upset one more time. 🙏 forgive me.

I’m learning 😞”

Any suggestions on how I could respond would help too. I never ever deal with confrontation so I’m not sure what to say
