Be careful with LM. Of course, do what works for you, but in my case, it was just sex. It was fantastic, mindblowing, monkey sex, but no love was involved. She even told me so. It has only happened a handful of times and now I look at it as if I picked up some whore in a bar and had a great time for one night. Don't really want to see her again, I got what I wanted.
My wife is not a whore. She is the mother of my children and the love of my life. The person who was fuc*&ng me was not my wife.
Don't get me wrong; only you can tell what's really going on. Just be careful. What you take as ML and becoming closer may not be the same way she is taking it.
