Are you sure there is no way for your "ex get back together plans" to work? Has he told you that he would not get back together with you if you were the last woman on Earth? Interestingly enough, the more he denies the possibilities, the better chance you have of changing his mind.
All you will need to do is listen to the reasons that he gives, and then figure out what he is really saying.
Today, almost every man will claim that women are confused, and really don't know what they want.
At the same time, men often start relationships, and then get frightened the minute a woman starts talking about marriage and a family.
The bottom line is a man will not commit to you unless you are able to reach him at a spiritual level.
No matter how much of an insistence they put on physical intimacy, it will not mean anything without a deeper attachment.
Therefore, if you are trying to make your ex get back together with you, it is very important to work out how to reach his deeper feelings and instincts.
If you go back over the past events in your relationship, you may discover a number of places where your knew that you and your ex were not connecting on all the vital levels.
For example, even if you agree on political issues, there may not have been a sense of mental understanding, let alone harmony.
Unfortunately, if you cannot achieve this feeling when you agree on something, there is no way to rely on a deeper level when you disagree.
As may be expected, if you are trying to make your ex get back together with you, then you will have to solve this problem first.
While it may take some time for you to figure out all the details, at least you will have a better chance of succeeding.
