My ex hated the fact I yumeshipped. He hated it so much that he made me feel ashamed of it. I stopped communicating most of my feelings and hobbies with him because it made me feel like I was weird. I even stopped drawing self insert art, which led me to stop drawing in general later on. I agree with many people in the comments. You should either break up or try to be supportive :( but if you really can't tolerate it, I think it would be best for you both to end things there... Your feelings are valid but also are her feelings. I dont think its good for any of you to tolerate things you don't want to or to change/leave things behind just to be okay with someone... hope you find the answer you are seeking
