Most Helpful Guy
Based only on what you've written, no I don't think your in the wrong.
It sounds like you want someone who is going to be there for you. Someone who you will be able to share a life with. From what you've said, it sounds like this guy is married to his job. I would guess that every day that he comes home, he is tired and probably doesn't have much energy to do anything. If his job is his life then it doesn't sound like he has room for you. Most breakups have an obvious reason. (the other person cheated, treated you horribly etc ). It's hard to feel justified when the reason isn't as obvious. I feel that he has someone in his life that's more important, it just happens to be his job. So in the end, it sounds like you are breaking up because he can't make you the number one priority in his life. We all have expectations of how we expect our lives to be when there is someone in them. When these expectations aren't met we have some options on how to deal with that. Break up, or change. If you don't feel that things will change in a way that your expectations will be met, then I feel there is only one other option left to you.
