Whats more important???? Being a otaku or my girlfriend???

2 scenarios. Which one you fall into is the decision I'd say follow through with.

1-You ignore her because of the your hobbies. This is negative. Do as she requests and cut the bullshit. Pay attention to her. She is not a hobby. Thus she will be angry when you do not do stuff she likes or anything at all, so long as you are doing it with her.

2-You do pay attention to her(no...really) and she a bitch who thought she could change your "wicked otaku ways". In which SHE does not respect you. So dump her princess sorry ass and move on with your life. Being told you cannot enjoy the things you enjoy by someone that hates them. Is hating you indirectly and that person clearly doesn't respect you.

Choose. Be honest with yourself. Then live with it. You can. Trust me.
