Will this help my chances or ruin them?

I was ghosted by my 10 year girlfriend 2 months ago. She was going through things at the time like being unemployed and health issues (non life threatening). She even cut off a friend or so she says she did. She was pulling back for some time and just kept saying shes “tired” and “exhausted” and has nothing to say. I have been financially supporting her for some time. Well i still continue to pay for her 200 dollar gym membership that I know she can’t afford. I wanna stop that but I feel bad? Will this make her miss me more? Or hate me more? I tried reaching out a month ago and got a response from her sister telling me “stop reaching out she does not want to hear from you she’s alive and well now please give it a rest in the nicest way possible”. She deactivated all her social media and im worried shes depressed and thinks nobody cares about her. I wanna reach out one more time in maybe 2/3 weeks because I simply don’t wanna live my life in regret. Will the gym thing help me or hurt me?
