Woman's point of view: Ggggrrrrrr! I don't like it. It sounds to me like she knows your feelings, knows you are available for her, knows you won't tell her no and needed to feel wanted. You care too much about her to be able to hold it back at only sex when she wants it with nothing else. For whatever reason, she has moved on but knows you haven't and knows that if she gets lonely, you will tell her you love her, she is desirable, you want to be with her--all the things an ego needs to hear. You are there for sex, which is also what she needed. But she is missing the emotional attachement, the emotional part of what you had she no longer feels, again for whatever reason. Just based on what you have said, you are setting yourself up to be hurt and that is wrong. You deserve better. Please take care of yourself and be gentle.
