How much time should we give a trial separation?
Well I think that if you have separated for a few months and you are not feeling any differently than you did the day you separated, it is probably time to move on. But if developmentally, you are starting to feel different about this person. You are missing them. You are liking them more. You are recognizing that life is not better without this person and that you are recognizing that you have brought many of the problems to the relationship that you think are there not just the other person then the separation probably can be lengthened and elongated to take as much time as you both need to make this relationship work. Ultimately, people make a mistake by reconciling too soon because often people will miss each other. Their sexual desire will be heightened by the separation. They will come together prematurely and then nothing will have changed and they'll be right back where they were except damage will have been done to other relationships including children and extended families.
