Update.
Thanks for the posts folks. Her son and her are open about sexual things, but she does not want something to happen on "her watch". She has talked at length to him about how to protect himself. She knows that things may happen, but she does not want to provide the opporunity for it to happen.
As for the recent developments-Well, we wrestled in the pool (she loves that sort of thing) and there was much laughing and carrying on. When it came time for bed, she put her arm around me (she knows this is how I like to sleep) and I kissed her (slight kiss back). I told her I loved her, and she mumbled what sounded like "I love you too".
Still no touches which we used to do all the time. I do not mean sexual touching either. I heard her say "thanks babe" one time, but did not know whether it was a mistake or not on her part when she was reading an email I sent her-it was the love chapter of the bible. I told her that was how I felt about her.
As we were going to sleep we had a conversation about what I miss about how we were. I said I missed the pet names, and the touching--just us. I should say that through out this we have been showering together in the morning as we always have. Anyway, when I mentioned that to her, she said that when she is angry she shuts everything down and it takes time to turn it all back on. I can appreciate that, but think that enough time has passed.....
As I said, Sunday we are going away--it is to be a romantic weekend. I just hope that it is the reconnection I am craving.
