i think you posted a similar thread in the relationships forum a month or so back, yes? if so, i think you mentioned that you get pretty regular sex friday through to sunday, and sometimes even on a monday. my thoughts were that she was simply tired having worked tues-thurs, and that sex on a friday, sat, sun (and possibly mon) is above norm for a couple

. the average (here in australia, anyway) is twice a week.
the other thing is that you seemed to be having issues with her hanging out with some of the people she worked with (her clients). it seemed to be a pretty big issue between both you and her a while back, and i wonder if it ever got resolved. i personally didnt see a problem with the behaviour you were describing of her, so i wonder if her wanting to "break free" and go get drunk and be promiscuous is a sort of rebellion against you kind of "controlling" who she can and can't socialise with? does she get time to go out with her friends alone, or a regular basis? or is thurs night through to mon night usually spent doing couple-y things with just the two of you, or socialising together with other people? i am not saying that you are being controlling and not allowing her to see other people, but it is easy to fall into that pattern and forget to break out of it. it certainly was something that bothered me a lot when i was with my ex, but because it was a pattern (it crept up on us gradually) it was difficult to be like "ok, i'm making an effort to have a social life apart from you". i think it's an important thing for a relationship to survive, especially (maybe?) when you are younger. because you don't want to feel like you are missing out on growing up with your peers (i'm 24 now too).
