Am I being overly sensitive or is this just rude?

My birthday is coming up soon and my boyfriend wants to buy me a gift and suggests I need clothes(I wear my work uniform more than anything and it's not a big deal to me) and a new coat.... I am not materialistic and to me it's the thought that counts. He doesn't know what to get..and I don't particularly care if it's just a candle or a card or something simple..or really nothing at all (I am not sure how he wouldn't know after 9 years..) Tonight he wanted to take me out to again, get clothes, but says I am picky with my clothes(I am not it's just difficult to buy clothes for someone else because fit etc) I have 2 kids and generally don't do this for them unless it's just a Tshirt(teenagers). He then made a comment that he had something in mind but it wouldnt fit me right now and he was thinking it could be an "inspiration" for me. I was extremely hurt by it but didn't say much other than well wow.

I recently lost 25 lbs and I am not huge. I could lose some more weight but I just thought this was a hurtful thing to say. I just feel like he's not making it about my birthday, he's making it about what he wants and himself... I may have not worded this right and there were other things that were said that bothered me but this is a long enough post. 🙄 Thoughts and opinions appreciated. ❤️

Update: Thank you guys for the input I appreciate it. I did let him know that I appreciated any gesture but I have a whole dresser and closet full of "inspiration" that I had before Covid hit and I moved in with the jackass. Sorry not sorry🤷‍♀️ Birthday for me to do what *I* want to do. New Year and hopefully back to my old self. (With my size 2s that are in my dresser, as opposed to my size 9 in juniors 🙄)
