It's best to admit your mistakes. You'll need to forgive yourself for your part in the breakup, then move forward to seek his forgiveness. If you lose your temper and say things you don't mean, pull yourself together as quickly possible and apologize sincerely. There is nothing weak or demeaning about apologizing. On the contrary, it shows strength and good character. But when you apologize, be sure you mean it. A disingenuous apology is worse than no apology.

Now, a lot of men will not be in a relationship if they don’t feel secure within themselves. This is especially true if the woman is someone beautiful and independent. For example, a man may pull away if he is not financially secure at the moment. This is something that may help him feel superior, confident, and not wonder if he is good enough for you. Also, he may have certain health issues that he is not comfortable telling you about until he figures things out on his own. Another reason could be instability and or unhappiness related to his job. This can be an additional source of stress and men tend to feel as though they need to feel confident or protected with their primary sources of freedom: Money, Health, and Work.
The steps to success in getting back together are very clear, and just like a formula in math, you have to the steps to a T if you want a successful result. You may have already heard about the hand-written letter (I’ll expand on this later), radio silence, and reversed dependence, but trying to figure out how to text your ex to get them to come back is not always a useful technique.
