Well, you didn't once say that you loved her, or even that the sex was incredible or something to indicate a salvageable connection, so I still say you two are not a good match and you should look elsewhere. After the amount of time you have dated her, I would think you would know how you really feel about her, no?

Maybe look into yourself and your background to see why you are a people pleaser. I mean that's all well and good, but in reality you have to do what is best for you in the long term and I don't think that should be getting back into a situation that seems so difficult to make work.
