The guy wants out of the relationship. He has other things he wants to do, and he wants to do them alone. There's nothing wrong with that at all. The letter writer needs to think about herself, and her daughter, and what's best for her daughter, as well as herself. "If he really loved me, wouldn't he beg me to go with him?" The answer is yes. But, look at it this way. At least he's doing this now, not somewhere down the line, say after your married. Move on. It's better for both of you to just move on.
