At no point does that post from Sgt. Dakota Meyer mention cohabitation. As I parse it, Dakota's mention of "living together in KY" simply means that the two of them are in close proximity, perhaps with Bristol Palin staying with his parents. As ansel12 pointed out in post #100 "Put a Ring on It", Miss Palin is vehemently opposed to "shacking up", "trial marriages" and any variant of sex before marriage.
Plus, need I add that both Meyer and Miss Palin are brave and 100% pro-gun?

It does seem like the liberal mainstream media would somehow discover this, but so far they haven’t, not in all the years of these kind of accusations being made against Bristol Palin by the crowd that spread on the internet that Trig wasn’t Governor Palin’s baby, that the Palins were divorcing, and so on..
