It just takes time. Wish there was a majic wand that would help, but trust is something that once broken like that by close people needs time. It took me a long time to not jump and go into fear mode when I saw a man of the same type/build and coloring as my ex. Then I found I still am drawn to that type! That took some T work too. As she said most people have a type they like but that doesn't mean all body types are the same underneath. She was right. Most long tall lean guys I've met since then have been a whole lot nicer.

I hope it can help to know that time does heal, the economy sucks and doesn't help how you feel. A goup at a safehouse really helped me and it was free.
Good luck and may time fly swiftly in some respects.
