Communication

My boyfriend and I have been together almost 4 years. And it’s an amazing and loving relationship. And I’ve never been happier. Although these last few months he’s been very irritable because of this new job he started. He’s now a manager. And just recently transferred back to the place he started at 10 years ago. He’s more distant and less connected. So much so he’s almost become emotionally unavailable. I’ve tried talking to him about it and we argue. Horrible arguments that we have never had before. I’m asking for affection. I’ve been asking to take a vacation so we can reconnect. He hasn’t even tried to look and see when we are able to. I don’t know how to communicate with him at this point. I want to fix this horrible thing that has infested itself into our relationship. I’m out of ideas.
