<human>: Can you summarize the given text in a few sentences?

I [19 F] have been with my new boyfriend [25 M] for about 4-5 months and things are for the most-part great. However, I'm going on an excursion for a month and a half in another country without him and I don't know if I want to be tied down to a relationship while I'm out and about.

He's great, we click well, but we're not even at the "I Love You" stage and lately I've been noticing some selfish habits that I'm just not sure I'm okay with (mostly having to do with experimental drugs in my presence). Not to mention I'm moving within a year/maybe 2 years, so we both know we're going to have to break up eventually down the road even if we were super successful.

I'm really not trying to complain here, but I'm just trying to gather some outside perspective on when to break up with someone who you know for sure you're not going to be with for more than a year anyway.

Halp.
<bot>: Things are OK, but not good enough to maintain a long-term relationship. Do I pull the plug now or wait it out?
