Well now that there's more to the story, just disregard my earlier post about just booting her. Just try sitting down with her and talk about her. If this kinda thing happens yearly around this time, (underlying motive)>>> maybe she lost someone close or worst case is sick and trying to protect you by pushing you away? Just don't be pushy or tricky about how you do it. If you love her , which it sounds you do, tell her because maybe she just needs that kinda kick in the bum to open up. Just remember.... DON'T BE PUSHY.
