<human>: Started dating a woman who I've wanted to date for a long time, finally got the opportunity when she became single.  Found out she has a habit of getting drunk at her house one on one with various ex-lovers (who are now just friends) on a fairly regular basis, and has preemptively made it clear that this is not something she's willing to change (it has apparently been a big problem with ex-boyfriends).  It's not that I think she's a bad person for doing this and she's also made it  clear that there is no possible way that she will, under any circumstances, cheat on me.

Nevertheless, I have neither the energy nor the desire to cope with the kind of feelings this will give rise to in me as our connection deepens.  And I'm also not interested in trying to change the way she lives.  So it's breakup time.

Of course, I harbor no resentment, and in fact I think her forthrightness on the issue is commendable.  My question is very simple:  should I tell her why I'm breaking up with her, or should I just say something vague about us not being a good match?  I'm trying to minimize emotional distress.

Can you condense the text into three sentences or less?
<bot>: Should I tell the girl I'm breaking up with why I'm breaking up with her, or just give vague, boiler-plate reasons?
