As scrapster said... BREAK CLEAN!! Don't talk to her for 6 months.
But first thing first. Do her the courtesy of telling her why. But you have to be
strong. She might complain, or all of a sudden become soft, mushy,
and sentimental... BUT you know WHAT you have to do!
If she's fine with it..then that's great. If not, you still have to do it.
In the long run.. your heart and mind will just get messed up if you
pursue the friendship as it stands.
I SOOOo identify with you when you talk about feelings coming back.
As long as they are there... and as long as they 'hamper' your friendship,
you just have to back off and allow time to makethem disappear.
Good luck!
