Find Start Logic Review

Most men find it very difficult to talk about their inner feelings, and this can very often cause tension in a relationship. While you will more often than not want to talk about problems, he will keep his feelings bottled up inside him, brood about it, which can, and usually does, end up in an argument. As soon as there is a problem in your relationship, you probably ask him over and over again what is bothering him, which he of course will interpret as nagging. This is most probably what happened to cause your relationship to fail.
Your ex is probably confused as to why you broke up, because he cannot quite pinpoint what exactly went wrong. So, just give him and yourself some time to get over the break-up, before you try to get him back. With all the hurt and anger you are both feeling right now, he will not be able to understand that it is because of his inability to communicate, that is causing tension in the relationship.
At the same time, have a good look at yourself as well and be honest. Your ex cannot be the only cause of the break-up. Because there are two of you involved, it is more than likely that you also cause tension in the relationship. You might find that one and off during the relationship, your ex showed regular displeasure at something you said or did, and was obviously not happy when this happened. Make a concerted effort to correct these mistakes, to ensure that they do not happen again. It is possible for you to get him back, if he realises that it is not only him causing the problems, and that you are more than willing to admit to your mistakes, he in turn might then be willing to do something about his mistake, which is non-communication.
The first thing you must do when you meet with your ex after some time is to admit to your mistakes and apologise for causing him any unhappiness. Also let him know that you will try your very best to not make the same mistakes again. Then, give him an opportunity to take the same action. If he still does not seem eager to talk about the problems that caused the break-up. Let him know, in a nice way, that his reluctance to talk about problems when they arise only results in tension between the two of you.
Let him also know that, above all, you want to get him back in your life, but if any problems arise the second time around, they should be dealt with immediately, so that arguments can be avoided. He will more than likely see the logic in this, and probably suggest that you and he get back together again, and give the relationship another try.
