I always have this theory, if you both first started as strangers, then when things end, let’s be stranger again. I see no point of staying in touch or communicate with each other. I would like to come clean for my next relationship, and it would only be fair to others. What’s the point of keeping in touch EVEN you broke off peacefully. The thing is, unless you want to create unnecessary doubt or cast worry to our partner, then go ahead. If that don’t convince you enough, give me example of people who have found happiness in relationship, if they didn’t cut free from their old ties.
