Different stages in our lives

I've been in a relationship for over 4 years now and it has always been pretty good. My bf is 3 years younger than me and we have known each other since primary school. I am 26 and he is 23. He has never had any friends and was confined to his house with his parents until I came along. Our issue has only started occurring in the past nine months. He has finally found some friends and is becoming popular in his own right, and is now part of the entertainment industry. This means he starts work at 2am and finishes at 6am. This is all fine except he has started going to work at 9:30/10:00pm every weekend. He says that it is so he can make contacts and become well known. He is not the kind of guy that would ever cheat and I 100% believe this. I have irrational jealousy over the people he works with. I also get very angry quickly because it doesn't seem like he understands me. He gets very sarcastic too. It isn't that I hate the people or his job, it is that I feel lonely. Also he studies Monday to Thursday and Works Friday to Sunday. They are all night classes and I work day shifts. The problem is that he doesn't seem to care about my interests or what I want, he only cares about his new life. I understand that he has friends which he has never had before, and that it is an exciting time for him. I just don't want him to forget about us. We have had a million conversations and it always comes back to the fact that we love each other and we want to end up together and we want each other forever but we are at different stages of our lives. We have lived together for three and a half years and have two dogs together. We had made plans to begin a family in two and a half years but we both think that our relationship isn't ready for it now. What I need help with is figuring out what we can do. We don't want to break up but something needs to happen. We are both stuck and would like some help. Our next stage is that we see a counselor and ask for help. I would prefer that we could make a decision on our own though. Any help would be appreciated. :)
