My mistake. In a way, if he's working, then he has even less time and energy for you. He, basically, was spread too thin. I'm wondering how old he is. It can be normal for a guy to go through a phase like this in his early twenties. If he's over 30, then it's a way of being.

It would be easier for you, if he was a monster. He's not. He's just not the guy you wanted him to be. That can be heartbreakingly disappointing. Then we have to remind ourselves that it's no one's job to be who we want them to be. Until after marriage, IMHO. The marriage commitment involves considering the impact on the other person of every decision. So that's what pre-marital relationships are for. They are to save us from disastrous marriages.
