I want my ex back after 7 years apart. She only shows interest when she feels like I'm giving up on her.?

We haven't seen each other for 7 years. I am moving to the city she lives in and have been talking to her on and off. She likes me to say things to her like that I love her and want her back, but will NOT tell me the same things, but when I tell her I'm having second thoughts about her and US, or moving there at all, she calls me right away to tell me I'm ruining any chance of us getting back together If I continue to have negative thoughts about it. If I don't answer, she calls and calls and sends messages until I do. Otherwise, she shows no interest at all. Fact is, that I AM moving there, and have no choice because of my job. She tells me she doesn't think we should communicate regularly until we see each other again face to face. We have both seen current pictures of each other. She tells me that she will be more attentive after I move there. Should I continue this pursuit?
