Welcome. I am also new and in a very similar place. She's on the couch and claims not to be talking to him, but says she can't imagine not having him in her life.
I've been backing off for a few days (but slip and talk a little sometimes). We don't kiss, but do hug a bit. She smiles more BUT seems to be taking the backing off as a sign that everything will be alright if we seperate.
I'm curious for the answer to your question: How does this backing off thing work? Isn't there danger to it- that I may be seen as not interested anymore or that I'm OK with seperating?
