My Parter says im not there for her can someone tell me if im not doing enough ?

My partner keeps telling me i am not there for her when i feel like i am , i do seem to go quiet when she goes quiet and i understand this part i feel i could be there for her that way a bit more , but in other parts of our relationship i feel like iv been doing enough , i bring her flowers reguarly , tell her i love her every day , always do small things to make her happy like pay for her hair or nails when shes getting them done , then in other parts of the relationship , i cleared all of her dept (thousands of pounds worth) , i paid for her to start her own buisness (dog grooming £5k ) then everything that comes with it equipment and a space to do it from , twice in 2 weeks iv had to ask her can i go somewere with her instead of her inviteing me and it makes me feel like im not wanted , she says im miserable to be with , my mental health does tend to get me down a lot iv been trying my best to better myself every day to make her happy , do i sound miserable to be with ? I need someones honest opinion because i dont know if im right or wrong and what she is telling me is really hurting me .
