Willing to invest in spoiling but not lifestyle ?

Need opinions, my boyfriend (M 43) told me that he will take care of me (F 27) and help me with anything I need and loves to spoil me, he's been doing so but I bought a treadmill for my home and made a joke about how he should've a bought it to which he says "Baby I think that the things related to sport, gym, tapis and wellness are tightly related to the motivation that one can have to achieve their personal goals. My opinion is that is important that the person pay theirselves for these things, because making financial efforts to get gym instruments or gym subscription are also part of the motivational process that brings to the achievement of the personal goals. Said with love" I just want you guys opinions on this because to me it doesn't make any sense and kind of makes me want to sort of distance myself a bit because I feel like the logic is missing and proves that he WOULDNT actually "do anything for me". Also he makes such an emphasis on how beautiful I am to him and everything so to me it doesn't make sense not to invest in your woman's beauty so she can be relaxed and not stress and in turn stay beautiful lol. Especially because he knows I don't make much money and since he's my boyfriend he doesn't give me an allowance just pays for all my stuff when we're together. After I pay rent and bills I only have about 400$ left for food and fun monthly. I feel like why almost starve myself or not be able to go out sol can V maintain my beauty essentially for him when I can continue my normal exercise routine and live normally. Also I forgot to mention earlier the reason I felt inclined to buy this is because he made "a joke" about how I could afford to lose a bit of weight "but not too much because he loves my shape" essentially. I'm also concerned he wants me to have no individual money leftover so l have to depend on him for everything and need to be with him 24/7 to get anything and like can't go out with friends and etc, especially because he made "a joke" saying that's basically what he was trying to do. Like for example, he told me to get my nails done by myself, and this, but for my hair he took me and paid and like I said, dinners, drinks, gifts, vacation. And with the things he's said am I overreacting and is he in the right ? Or is my concern valid ?
