SP - I just have to chime in here about the arching the back thing....
I'm in a good relationship right now with no infidelity or anything of that sort. However, my man has trust issues from his past so sometimes he "sees" things that aren't there. His fears cause him to imagine things that aren't true.
Several times in our relationship, we've had friends over, and during a pleasant, normal talk, I might stretch the way you are describing (arching back). Everytime this has happened, my man has given me "the look" which means "knock it off", and I have at first been like "umm....what did I do?" Later he would tell me "don't arch your back and make your boobs stick out like that, it drives men crazy!" I didn't even realize I had done it, but I certainly stopped doing it at all eventually.
In my experience, all I had done was stretch my back after a long day. I would have done this if no one was home, too. But in his mind, I am making a subconscious message to our guests to check out my boobs.
Soooo....all I am saying is that what looks like a subconscious message to you may only be her stretching her back.
I'm not saying she isn't giving you sexual cues, because I do think she is. But I'm just doubtful that this one action is one of those cues.
You have heard the expression DAM (dumb ass man)? And understand how there are certain things that men do which they just don't realize are dumb, but which women certainly have a problem with. Well, there are some things that qualify as DAG (dumb ass girl) actions. Things that - being that we are not constantly watching for sexual cues for the most part the way men are - we don't realize may come across that way. Especially with the man you've been with for so long, we eventually come to believe that they don't really notice our bodies the way a stranger does. And we frequently don't realize that men notice boobs at all. That may seem silly to you, but it just isn't on our minds all the time so we kind of forget that boobs are such a big deal. (This doesn't necessarily describe me, but I think it would apply to most women).
