I just finished mine up as well, came home from a trip and most of the shit was gone, totally blindsided, I would have never guessed it would happen. I can say with incredible confidence that it was the BEST thing that has ever happened to me, I thought I was in love, but I was fooling myself. I walked away and chose to protect myself financially and mentally. I cut off 100% communication with her and found peace and understanding in the Bible and Church. I met the person I will spend the rest of my life with about 6 months later and this is the happiest I have ever been in my life without a doubt. God works in mysterious ways. If she cant be there for you and talk to you about the problems, is that really someone you can trust and someone you want to spend the rest of your life with?! Never settle, and never stay with someone just because of the time invested in them and the false security. Although I should be better than this, I did take some enjoyment from when we (Megan and I) ran into her a few weeks ago; the X was looking rough, and Megan was looking hot as usual

Best of luck to you in whatever path you chose, many of us have been there, feel free to vent, we understand your pain.
