I'm her friend but she doesn't like me !

I recently became friends with the girl from my work she got hired for assistant position , she is assisting my boss. I have invited her to the house cooked dinner for her , introduced to my family. She is single so I'm trying to help her meet people . And she has some extra weight , but I think she is really pretty . She asked me help her lose weight to meet a nice guy , she is 30 now. And I have helping her , providing nitrition plans , taking her out to the nice places helping her buy clothes letting her borrow my accessories . Anyways I'm being a good friend. But she doesn't seem to put to much effort , she goes to the club with dirty hair , no make up , dressed up weirdly ( unless I prepare her in advance) and all she does later is that no one looks at her and that she is 30 and single. After I put so much effort to help her with preparing healthy smoothies , salads, food under certain caliries , I see her with the fat chocolate something huge coffe from Starbucks with a lot of w cream. Same thing repeats later I take her out and she doesn't take care of her looks and keeps complaining that Noone likes her. I asked her to go with me t the gym but. She prefers to watch game of thrones with bag of chips. Lately she hasn't been talking to me that much and when I ask her visit me or go somewhere she is rejecting me . My husband told me she might be intimidated because I'm successful, I have MBA and degrees. I have to admit guys want to talk to me more then her but hey my feelings are  really honest , and I want her to be happy and healthy and help her with all my heart . I spoke with out VP so she could getter a better job and she did , she is not assistant anymore , yay ! I just feel like I want her happiness more then me and she gets annoyed by that 😔 what do I do .
