Gf [23F]Uninterested in Intamcy with me [25M]

For context we’ve been together nearly 2 years now. it started out great, Sex couple times a week but now after she has moved in i’m lucky to get action once a week and it is always on her fridays never any other day which makes me feel like just a chore. I’ve voiced my concern about the lack of sex multiple times but it’s the same story every night. She eats dinner then scrolls tik tok until she falls asleep on the couch. she claims it’s because she doesn’t know how to initiate intamcy but even when i’m the one trying to touch her and kiss her she always just pushes me away and says i’m being weird. Any Advice is greatly appreciated
