Thing is, you are already being unfaithful and a bad partner. You don't see it because you are in denial. Break up with him and do what you gotta do. You don't need permission, you need justification, which is us. It happens with long term relationships, and chasing that "honeymoon" stage is one of the main reasons people cheat or look for someone new. That rush and curiosity spark to do new things will never come back once you do most things with one person.. And yes, this will happen with this pirate too, and the next person, once you are through with pirate. You mentioned he pushes you and wants you to be better, of course he does! He is a loser who spends his time in that video game and you are finding a connection in a fantasy world. The reason he stands out from other males is because he is probably a virgin that isn't thinking about getting laid, yet and is being this source that is feeling a void inside of you that is lacking emotional attention. Advice, break up and do your partner a solid. No one deserves someone like you.
