If you and your ex-boyfriend have broken up before, then there is a good chance that your ex believes you have talked through your problems and tried to resolve the issues enough times before. So, no need to rehash the situation again. Under circumstances where you have had multiple breakups with your ex it is very likely that he believes that everything that can be discussed, has been discussed already and that there is no benefit in having the same conversation repeatedly. I remember a time when I broke up with someone many years ago and we got back together a few times. Over the holidays they rang every single day to try and negotiate their way out of a breakup. Eventually I stopped answering their calls because I found it annoying but also because everything about the relationship had already been discussed many times…. I had no new information I could give them. If you have broken up with your ex-boyfriend several times before, he may think that you don’t need an explanation as you have already had one and know everything there is to know.
