Should I be supportive of her decision to end the marriage? She expects full cooperation of her decision...WTF

The problem is, its a one-sided decision. I loved this woman with all my being. I never wanted it to end and had no idea she did either. She asked for my help in finding a reasonable location as to so I wont be so far from my baby. I want to help her at any cost, as she is everything to me, but this is something I feel I just cant do. I can not imagine helping her out of my life. I know she says its over and sooner or later Im going to have to accept that, but now is not that time. Im afraid that if I do not help, then she will resent me and do things to spite me and interfere with me and my daughters lives. I do not want that to happen but in the same light I cannot stomach the act of isting in even the littlest task that moves us even an inch further away. She says if I really love her then I would help her. If she ever loved me, how could she ask me such a thing without knowing how that would hurt me. Do you think if I help, it will it help me accept the fact we're really over?
