I think WASs say things that make sense to them. They may not make all that much sense to the LBS, because the LBS is on a different page then the WAS is, and thinks differently, and also has a different perspective. I think also WASs probably could have a list of the "dumb" things LBS they've heard their LBSs say (and do) for sure!
I think understanding what the heck they're saying at least clears up some of the WTF? type moments we LBSs have. I and a lot of us have heard that "I need to find myself and I feel smothered" only to have them run off with their affair partner much to our bewilderment as that seemed to conflict with their statement, yet understanding what they're really saying is, "I feel smothered in THIS relationship with YOU and feel freer to be myself and feel more independent with this other person", it begins to make sense. Then further understanding that under that, what they're saying is, "I can't figure out how to make this work for me, and I've been unhappy as a result. I don't really want to leave and be alone, because that's scary and I don't want to be lonely, and this other person makes me forget all that and gee, makes me feel so good when I compare it to the way I feel about our relationship, so I believe this is what I want", then the meaning becomes even clearer.
