Most Helpful Guy
You're being played. No, you should not spend the holidays together. He is not using this time to 'find himself', and that once he does he will return to normal and marry you. He is using this time to play the field. If he finds another girl, and falls in love with her, he isn't going to turn around and tell her 'Sorry, I know we've been dating for a year now, and that we love each other, but I'm supposed to marry somebody else. Hope you don't mind...'
He is using you as a fall-back plan in case things don't work out. He knows you have feelings, and that those feelings are going to make it hard for you to move on. So it gives him a lot of time to experiment and see who else he can sleep with before he has to start having more difficult conversations. He is 'redefining himself as a man' by saying he wants to fuck other women, basically. That does not show any sort of monogamous commitment to you as a person.
IF he was actually into you, and actually behind the idea of marrying you, he would be able to stay monogamous while figuring out his financial shit and spending some time away from a relationship. He isn't. Look at his actions, not at his words. The actions will tell you what he is really thinking. And his actions are saying he wants to sleep around. Those are not the actions of someone that has found their future spouse.

My ex said the same thing. but he has been single ever since we broke up which was almost a year ago. He only had one night stand 6 months ago, and that was basically girl throwing herself on him. He had many other opportunities but he rejected it. He keeps saying he wants to be single, and I do believe him. And that's the only reason I can still maintain a contact with him. No pressure, all cool. But I know for sure that I would cut him off if he was "exploring". In the meantime, I live my life and I am surely not sitting around waiting for him. I do love him and I am willing to make it work, but I'm also fine with meeting someone new. I'm focusing on my career and my hobbies right now, I'm not gonna move a finger for a guy anymore. :D
