I am friends with my exhusband now but it took along time. It depends on what kind of relationship you had and what happened to destroy that relationship. In my case he was sleeping with the neighbor while I was at work. In addition to the threesome going on my daughter was abused by the neighbors. It took a long time to forgive him but with God's help and major counseling I was able to. On the other hand I am friends with several people that I at one time dated. Just need to have a little time and space otherwise you may find it hard to put behind you
