Girlfriend gonna break up with me?

[Eduardo]

So lately ive been feeling that my girlfriend is gonna break up with me. and i really dont want that to happen cause lile ya'll wouldnt understand but shes been with me throught everything and shes perfect. but now i feel like shes tired of me or something. she used to reply with like 50727293 hearts. now she usually does one. and when shes on twitter shes always tweeting about stuff that seems to relate to us. maybe just crazy or something. but ive tried talking to her and she says she still like me but i feel like shes just saying that so when i fully recover from the brain surgery i just had and she sees me happy she can leave. am i going about it the wrong way? what should i do or ask to make things better? cause i wpuld give my life for this girl. and i dont want to lose her. shes my best friend and girlfriend and shes just amazing.
