I have to say that your beach date sounds more strained effort than anything... at least you made it through the day with nothing that seemed... damaging...
Just to point to a few things, that as Sandi2 will attest, a WAS in an A will generally be pleasant to be around when the A is going well and will be unpleasant when the A is going bad...
Not too sure that the beach date was a good thing or a bad thing, but again... you survived... interesting about the kiss... she may have simply felt "obligated" to show the affection...
So you two are living in different houses, correct?
How often do you see each other?
Is it possible that you have enough contact that she can notice the changes in you?
You mention weights, what else are you doing for 180s and Gal... sorry, not sure if you've mentioned them above or your other thread, but if you could restate them...
