Most Helpful Girl
Its possible she is testing other waters. It sounds like you could have been marrying any time soon, and maybe she got cold feet and wanted to check she wasn't missing out on something. Did you ever have similar feelings to this? I think she still loves you, 5 years is a very long time to be together and then suddenly not, that's a very big shock to the system. However I really do not think she is going the right way about it. She knows that you love her and want to be with her, yet she seems to want her cake and eat it. That really is not fair on you, because you are left guessing, wondering and not being allowed to make any firm decision.
I know she has already balled her eyes out when you said you were moving on, but you need to be strong, that is a very manipulative thing to do. How can she be there giving some guy all this attention and aspects of a relationship and then just keep you in the background like that, it is wrong. Tell her straight I can not do this anymore and disappear on her for a while. You will soon know whether she loves you or not. If she comes back to you, you know she still loves you, and if she doesn't you can move on knowing that she no longer does.
Wish you well :)
