She misses you simply put that is until you two are back under the same roof again for a time. The old person who insulted, yelled, screamed and did everything you didn't like will come back. I speak to this topic because I have been in similar situations over the years. My advisers cautioned me about going back and I too sent the sweet "I love you" and "I wish that things didn't go the way they did..." The point is a relationship as long as yours was takes a very long time to move beyond. Each day make yourself take steps to forgive and dare I say it forget. It's painful it keeps you up at night, sometimes ill, you hear a love song, see a movie...you feel crazy, but I tell you if you make an effort each day to preoccupy your mind with something other than her you will be fine. Also when those thoughts of her do come, remember all the false promises, the ugly words, the yelling...a leopard doesn't change its spots.
