Yes, that is usually how it works out. In my case, I kicked my husband out and had him file for divorce. He shortly there after, before to divorce was over, he hooked with my friend/ex boss. And marries her shortly after the divorce. Then mutual friend chose sides and I lost him too. So I understand kind of what are going through. I thought everthing would work out where we could all stay friends, but that didn't happen jealousy made impossible.

It's hard to lose so much at one time, but don't lose hope. There will be new friends. And for a while you will not be able to trust but later on it gets easier.
