<human>: I've been in a relationship for almost a year now.  He (28) and I (28F) are about to try a long-distance thing, as I will be leaving for school at a city 1.5 hours away.  I will be gone at least a year, perhaps a few months more.

In short, I don't think he will be faithful.  I can't say that he's cheated before, but he has a history of lying about other girls he knows, and not telling people at work that he's in a relationship.  He flirts (lightly) on facebook and through texts to co-workers.  Nothing overtly sexual, but definitely suggestive.  His culture (Middle Eastern) is very accepting of male infidelity, and although he says *he* doesn't condone cheating, he admires figures like Bill Clinton for being "real men" and sleeping around.

On the other hand, he talks about wanting to spend the rest of his life with me.  I don't think he means this, and frankly, I don't think we'll make it another 12 months.  It feels like an ice pick in my chest, but I can't lie to myself.

So, my question is this:  Do I emotionally separate, "pretend" like we're doing something long-distance, and carry on with my life?  Presumably, it would be a "don't-ask-don't-tell" situation.  Or, should I break it off now?  And what should I say?  Should I be honest, or give him the "let's go out on a high note" talk?  Or, am I being paranoid?

I thought I loved this man.  It's really killing me.  But, my instincts are telling me to get away.

Can you give me a shortened version of the text?
<bot>: BF has an unfavorable history of flirting.  My gut is telling me to end the relationship, but I'm afraid I'm being paranoid.
