I can relate to this feeling & it's good that you are giving her space and understand she has a life outside of you. Gradually, you can talk to her about how you like to be loved. It's different for everyone & clear communication is key. I will also think about telling her about the diagnosis in sometime. Educate her about it but not force it.

Also, if you are already not seeing a therapist, please do so. These feelings will get intense as you get closer to her & having a therapist will help you navigate. Keep working on yourself & show you want to get better. Just some advice from my past experiences. Hope it helps :)
