<human>: I met this really great guy while at a trivia night with my friends back in December. Expected it to just be a one night stand but we have been hanging out ever since. We discussed from day one that this was just casual because I wasn't looking for anything serious since I'm in a rotational program where we change locations every six months. I'm due to leave in May for the east coast. 

Both of us have been exclusive and it basically is an accidental relationship at this point, except the rational part of my brain keeps telling me to bail before either of us gets even more attached. Does anyone have experience with this? 

(Note: Long distance is not an option as it would be indefinite since after my program is finished I'm 95% sure I'll be staying on the east coast because that's where HQ for the company is. He also has zero desire to ever leave the Midwest. We also have both been in long distance relationships before and have no desire to ever do so again.)

<bot>: Relationship with an end date - ride it out and enjoy it while it lasts or call it off now before real feelings come into play?
