Well, that's a tough one and also sad because it seems like you are having some kind of second thoughts and second thoughts are not a good sign, how can another guy even come into the picture if you really loved your boyfriend, but you said that you are falling or already fallen out of love, so I guess it was going to happen that you feel attraction towards another guy but now you need to decide what you want, do you want to break up with him because you have fallen out of love? of course there is no point in being with someone you don't love anymore, Okay now let's move to the other guy that you mentioned
Do you know the other guy even likes you or what? Do you know for sure you have feelings for him or is it just the attraction. infatuation? What if he has doesn't have any feelings for you, then what?
Hence, I would think about all this, know what you want and then take a thoughtful decision.

Judge after the holidays with him, if you really are in Love with him maybe it is jist a moment of boredom or that you are far from him (I mean by feelings not distance) or that maybe there is something you are missing in your relation or that what made you fall for him got lost by time, so I suggest you to give it time and get more closer to your boyfriend to know what actually happened :) talking it with him would help too if he is not the rushing type ;)
