So here's what happened to me when I had a conflict with a good friend.
Actually, she was my BEST friend, all through high school and college and the Maid of Honor at my wedding. We were together through everything, but after I got married things started to slip.
I let it go on for a few years, but there was one thing that drove me nuts: I went to work after college, and she went to grad school. So at the age of 26, I was married, working full time and had a mortgage, and she was living on a shoestring getting her Ph.D. And yes, I was expected to pay for EVERYTHING, from trips to visit her to dinners to long distance bills.
After a while, I finally, cautiously broached the subject of the phone bills. We were talking for almost an hour one day, as we did about once a week, when I mentioned that the long distance bills were killing me, and I should get off the phone.
She hung up on me, and I haven't heard from her since. That was in 1994.
Later that year, she told a mutual friend that I had told her that my husband wouldn't let me associate with her anymore.
That's when I decided not to worry about it anymore and just move on. Some friendships just aren't worth keeping.
