I also sense an attitude of "she has a loser boyfriend" and getting some very mixed signals about that - BF is clearly no good for her, but they should move in together (away from their parents). Maybe if they moved in together he'd suddenly prove his worth? (And, nb, this is my read of LW's opinion, not my opinion, because there's nothing in the letter on which to base an opinion, other than a promise ring, no rent to parents, and partying every weekend (with the insinuation that they're sexing it up contrary to his wishes, which bring up a whole nother ball of wax).)

I kinda want to shake every LW in these things and ask them, "WHAT ARE YOU NOT TELLING US?" Because these things always have such conspicuous information holes, and it's hard to try to figure out what goes into them.
